But know the disease of fart
The titration is correct, and this is the Ido metric titration. It is correct, so basically
The most important title for you will be your own sovereign title.
Now in titration, what do you see? You're given a paper sheet. On that paper sheet, you're not given an M.
Apparatus and observation tables are prepared, that's correct; you just need to fill in the values. But how will the values come in?
How to do everything very deeply given, but for calculation purposes
I would like the calculation to clearly show the partial titration, in which I have mentioned some short points.
Because I have already explained how practicals are done, how readings should be read, and how the final result is obtained.
There's another value in it where I've explained the titration calculation for Mohr's salt, so you can understand how to perform the calculation.
What needs to be done in titration? You have two solutions, one solution
One solution lies within your beauty, and the other solution lies within your conical path, meaning the tightening.
If you look at it, you'll understand those things, yes, certainly I'm coming right to the salt because
First, I'll authenticate you with Anayns' salt. One is your co3.
If a carbonate test is performed, how would you determine whether carbonate is present in it?
So, take your salt, put it in a small tube, and add a pinch of it. Just a little salt, put it in the tube, and add a pinch of it.
If effervescence occurs, bubbles are generated.
Bubbles or effervescence are generated
So you will understand what carbonate is present in it
These are salt tricks.
Effervescence, you understand, you've had a Sprite bottle, what will remain?
Many, many dolls come.
That's too easy, I mean it's very easy.
So how will you do it?
Sem, you have been given salt.
Add barium chloride to it, BaCl₂
If you obtain a white-colored precipitate
precipitate If I were to tell you
What is precipitation?
precipitate basically at the bottom of your test tube
A solid material in white color will fit into the bat.
If something like that were to happen
I've said it many times: make an OS
Do you know what an OS is?
You have a watch glass; salt is placed on it.
Any salt will do.
Put a small amount of salt into a test tube and dissolve it.
That would be your OS.
You have to test using the same OS.
First, please listen to my entire salt video.
After that, I will take all your questions.
First, let me tell you
Because I've done extensive research and created these items myself
Pay close attention to what I am about to tell you first.
But the one that is chlorine is the third one.
Testing for chlorine is also very important.
Do you know what happens to chlorine?
If you add concentrated SPSO 4
concentrated
Just a little bit
Put a small amount of mixture into your test tube.
And if you add concentrated SPSO 4
So if a lot of gas escapes
If in your laboratories your test tubes contain
A lot of gas is coming out from it.
It hints that chlorine is present indeed.
Because chlorine gas spreads very easily
So, this is your chlorine test.
What happened to you, friends? Test for chlorine
Now in this
There are two or three more tests, one of which is for acetate.
CH₃COO⁻
You must have seen vinegar
Vinegar means use in abundance
Used at the Chinese Center and the like
The smell of vinegar tells
Produces it, then if it has a smell
So, the acetate group is present.
So these things
You can find out by looking at the salt.
You need to do the physics practicals
And doing Chemistry practicals
You've been stuck for over an hour on the physics practicals
You've been stuck for over an hour on Chemistry practicals.
The total time allotted to you
May had already taken the salt before the year.
Original solution
target
mixture
Salt
It appears to be white in color, some color of salt appears, a solid material appears
If you put it in your QR code reader and added a little water, it did
To dissolve the solution that is prepared
It calls it the original solution; what do they call it? Original solution
Okay? Yes, you can tell from the smell
I am telling you the CT's direct test.
CT, you're a cockroach. Only CT, if you become one, you'll get it, right?
I want to tell you the first things first, okay?
Just a little bit of leiz, add water, and your OS is ready; diluted and BACA2 have been added.
If a white precipitate has formed, it means SO4 is confirmed; please write this down.
CO3 has been stated, what will happen in CO3?
Bubbles will be generated after adding to dilute.
I've already told you about chlorine; after adding CO2, a lot of fumes will come out.
It becomes clear that there is chlorine there.
I'll clarify some other things for you.
As if there are some gases
If you place the mixture into a test tube and heat it directly
For the mixture, nothing is needed in the test tube only
Nothing is needed for water; a dry test tube is required.
You directly heat it in the blue flame.
So if you get brown gas
So, what will the nitro group, NO2 group, become?
Your present will arrive.
What are these things, vaccines, NO2, or NO3?
Vaccine
These things have happened, I think
This is enough for you.
There are so many things coming in, and it's way too much.
The importance was yours, which I explained to you
Here, anions' vaccines
So I think I've cleared up everything about anions.
Tell me about PO4, look into PO4
Someone has asked, Subham Singh
Tell me about P.O. Four, look
PO4 was very important, I don't know what I forgot, sorry
But look in PO4 for this vaccine
You shouldn't have done that; you should have taken the mixture, you should have taken what
Just a second, look, your private
It would be very much if done, you one
Take all the ingredients, add the mussels to it, and add them together with it.
Quantum entanglement is a phenomenon where particles become interconnected, and the state of one instantly influences the state of another, no matter the distance between them.
Just boil it a little, and there it is right in front of you, in the lab.
What will the resident hold for ammonium molybdate solution?
Ammonium molybdate solution stopper
It would have been put into the bottle; if you have it
canary yellow precipitated, you wouldn't know, would you?
What is canary yellow precipitate? So, what exactly happens here?
It is a very light yellow color.
The light yellow color won't let it sit down below.
The solid color substance will settle down once and then I
I'll take a small amount, just a little bit light
Just a little heat, just a bit more added to it
ammonia solution if you get a yellow-colored pipette
Pipiti means it settles down solidly below.
Test chup is okay, then you'll understand your
Yes, someone commented on physics among the five.
When I was doing practicals, I hadn't seen a single channel.
I'll tell you what those channel people are doing.
They are taking him there to the practicals lab.
Telling them to put this here, put that there, this one, that one.
So, what's happening when it comes to children? I mean, what's going on with putting them under?
I mean, things should be empty, they should be empty
What needs to be done for this test?
I was watching one of their videos, that's why
How many children are there under the name of this skill test?
Luga, but when you finally catch the testu there, you'll feel a different kind of frustration, wondering why you didn't catch it earlier, right?
I'm just keeping up with all the tests, okay?
In C.T., all the things become blurry, they turn into glare
So I've gone ahead and clarified your Anionce quite a bit, and this is all very important regarding Anionce.
No other anion remains, sir, CO3
I already told you about CO3, didn't I?
What do you need to do in CO3?
That is your mixer; you need to take it and put it in
Add diluted H2SO4
If there are bubbles inside your test tube's liquid
Bubbles start to form
First, I'll take the courses related to this.
I have completed the course in 3000.
Lying down
I understand all this stuff
Because I have seen so many people
Videos
It seems he doesn't have a science background.
This is being taught in the backward class.
What should we do? They were there.
You will pass if the score is reduced by 50%.
Yes
But you don't give your best
In the copy, write "city bus"
No, you don't go there
It is given column-wise what you need to write.
Which tests to write, those will be given there
You are constantly being given a box.
You have to fill it out.
Yes, I was about to tell you right here on the board.
What happened was that transportation had been shut down.
Due to which one of our lives is live
There was nothing wrong with the studio ahead.
So, to bring that equipment
Now also
Four to five days and I'll be gone
Not even once before twelve o'clock
I'll come live, so that I can get on the board directly.
That's our entire instrument; that's our setup.
YouTube said you should add a little VAT.
Certainly for him
Now, regarding the iodine test, many children have problems with the iodine test.
So, look into iodine—what are they, the iodine test if you need to find out
The iodine test detects iodine-related problems.

Chemistry practicals for Sir Liberator's students
They will give such marks
Make videos with so many sixes
Yes, I'm totally seeing you, you know.
I keep pouring salt continuously into the video.
This is all for you in the realm of chemistry
Tell me or I'll have to do it myself
You'll need to recall chemistry a little.
You can learn just by living here.
So I've finished your letter.
Now I'm turning your mood toward the direction of Catan.
Let me tell you my second one first.
You wait two minutes on the bus stop and listen to my words carefully.
So I finished Anayans.
Today I am taking the entire chemistry exam.
I'll look at physics on another day.
Because speaking repeatedly has really started hurting my mouth.
I'll show you how to find the test for Catan.
Look, if you're watching my video
So I keep repeating the word "group" over and over at that place.
What is this group?
Because look, all the salts that exist are ours
Cu²⁺, Pb²⁺, strontium, barium
So they have been placed in separate groups.
So that we can detect it accordingly
So the first one is our zero group.
These are the kinds of people we have in our group.
So, what is the Zero Group?
In the Zero Group, we come to know this
that our NH4 presentation was
Let me tell you what you need to do for this.
You have logged in to the OS.
Install the OS, then install AnyOS into that OS.
Put a small amount of the salt you have into the test tube.
Just add a little water, and your OS will be installed.
Install AnyOS on it, apply the patch, and then heat it.
If it had turned out to be a termite infestation in the brown pepper.
Understand what NH4 is present in it
Your Zero Group presentation will arrive today, and I'll take its CT.
What is the vaccine in his CT basically?
What is in the CT of Zero Gravity?
Let me first clarify this here — please take note.
If your salt contains PB, don't take the PB vaccine, if you have lead then
It remains plus, the delta steel remains, if you have
What will your Group 1 become if you get the White PPT?
So, you can do CT for Group 1; what about Group 2?
You will create your own OS, install it, and then your
SOS gas will appear in the Bhaju, they will indicate the vaccine, those people
So, these CU tests are very important and appear quite often.
Now, before I finish Salt Pura, let me tell you a few tricks—take a look.
We can also find out based on the color of some salts.
If you see a blue-colored salt in front of you, understand that it contains copper.
Does it contain copper, and has a copper test been conducted?
If you come across green-colored salt, you'll understand.
that it should be your pale green, meaning very light green
Very light green, light green
So you understand, your F-E is present in it.
You understand what's in it, F-E present
If your dark green stays, one dark green
So understand that it contains nickel.
It will be very light pink.
So you understand that in it, yours
Mn is manganese.
So there are many such salts that I am giving you
I'll tell you the trick, you'll write it down, then you'll have it yourself.
You can find out in the exam
If you have found the group, then you can have your
Recreate the OS from the backup and
Whatever reagent needs to be added in CT
As in Copan, performing K4, F3, CN6 maneuvers
So, Darakali, please be cautious, if you're feeling brown
It's the chocolate brown one that matches.
Got it, now I understand then CUT
It's a trick, isn't it? Sir Astrey, tactical
We will discuss the theory, Sir and Vikie.
I'm trying to make it right now
For Salt Press Vote

How will columns appear in chemistry?
If you hadn't been writing to me
Which tests have you taken?
oar
Writing for testing purposes
You are given a book sheet.
All the tests are written by me.
If you're receiving something as a gift
There would be 3 columns among these
I am a test, observation, inference
Create a 3-column layout
I am a test, observation, and
inference
So, test, observation, and what else?
What exactly can you check using this inference?
Test me dekho aapko kya likhna hota hai
You have to write to me.
you mentioned like OS, DALU, DECEL
Oh no
What is observation? What did you get?
Observe, whatever things you will receive
What is inference in AI?
result
I'll tell you once again
test, observation, inference
What should I write?
Test me, you took the test, took the OS, added NH4Cl, added NH4OS
What did you get?
Black PPT Mila
Anyway, whatever PPT I get
It will keep showing you
What is a test?
Now we proceed to our next step, the functional group analysis.
Functional group analysis also comes naturally to you, right in front of you
I will explain to you the FT-FT functional group analysis.
You need to focus on 3-4 functional groups, one of which is the carboxylic acid group.
Who is Subham official?
Subham, official, I want you to
I am talking to you
Since when should I start watching you, sir, provide chemistry practical theory
While I've already told you that it will take a little more time.
For setup, I need likes within 15-20 days
Alright, I'm going to tell you about functional group analysis.
Provide
The vaccine and its syringe into it
So if you get this red blood color
Red blood color—that is your observation part
Red blood must be written
What will the ketone become then project
Vaccines and one other thing, yes
The taste of aldehyde was there.
The taste of aldehyde is very easy.
You need to take a sample.
Whatever is provided to you by the salary
Whatever is written will be provided
Both writing and speaking are possible.
Take it and put it inside.
You will receive a silver mirror image.
I mean, do you understand what the silver color looks like?
If the silver color starts forming on it
So, understand what your aldehyde is
Is present

Palakhar District
Alright, let me show you. Hey, just zoom in a bit on the 7-20 area, please.
Show me, what test is this here?
Test, observation, inference — these appear here
Test, Observation, Inference
The test that will come in the exam will be
Whatever observation comes in the observation field
whatever inference comes in the aur inference
Look, this kid took all the tests from the beginning and still hasn't gotten anything.
Look, look, in the end, it turned out to have an amino group present.
Whatever color appears in the amino, it will be written down.
What will come at the amino group here? It will be present.
You should write it like this.
test, observation, inference
What test, observation, inference?
What test did you perform, what observations were obtained?
What inference did you draw?
What are you observing in the template?
Color is coming, precipitate is coming, what is coming, and in inference, absent present should be written.
Something like this happens, it's a column computer solution analysis practice
If you are to write a presentation, this is for preparing the Mohar Salt.
And how is Sep in Las?
"Sep" means monoclinic.
So you have to write the SEP.
Sir, do you need to react?
No, you don't need to write the reaction.
Sir, when I first cleared the exam
I've been watching your videos since then.
So thank you so much
You're watching my videos, that's correct.
So once again, I'm telling you clearly, I'm telling you with full conviction
The ones I cut with CT
I have been doing it for a very long process.
If you're getting Group 2
A black precipitate is forming.
So, what do you say?
Take your OS, please.
You're gathering together for all of your group
If you miss it then
Be sure to check the bag in the video.
Because these videos will remain on this channel
And on this channel, everything you need for your daily routine
As the Physics B practicals and Chemistry B practicals were
If you go there, you'll see, in the Sahi Steeje, there are many people gathered together in the scheme.
Why is your sponsor here?
Okay
Create a playlist for videos about surfing, sir.
Okay, make a playlist for the important ones, for the guys
Alright, I'll give it a try.
Sir, how many marks do the college people give if someone attends the practical session immediately?
Even if your practicals are delayed, you'll still do well.
Well, it depends on your college.
Many college students helped those who couldn't understand it.
Okay, don't worry, just practice well.
By 20, by the 20th to the 21st, they should meet then
I'll take care of all the doubts of the BRC children first.
I have come for those children.
I'll take care of all the doubts of the BRC children.
The children who have joined late just now
I will make a small request to them.
I have said a lot of B stuff here
You must definitely check it out once
Alright
What is CT?
CT means confirmation test
confirmation test means
As I've already told you,
If you watch this video, you will see there
I assume that my Group 2 has already arrived in the group.
So Group 2 has arrived, so you
I mean, we need to confirm one thing about him.
Yes, it is Group 2.
Then create the OS and go see Group 2
Which region, when added, makes it confirm?
So for Group 2, like
4 FACN 6 need to be added
If the chocolate brown pipiti comes
So, what will happen to this group of yours?
This is exclusively for BARC students
I'm making this entire playlist
I'll take a few comments
Tell me the salt trick of salt analysis.
Coffee with fur
I told you, didn't I?
As I speak, so I am looking.
You will have videos
Now I'll start streaming.
I'll upload it.
You're going, wow, I was talking about salt
Make a note and tell me, make a note lying down, make a note from yourself
Alright, these videos will remain with you, for the children.
If you have any doubt, please chat in the comment box, okay? Comment box to me
Comment here, I'll take care of all your doubts, okay?
This is not about you writing aim theory or distant salt analysis.
In salt analysis, I told you not to show it—I'll show you exactly how it's done.
Look here, look here, how CT is written here, let me show you
You can see it
Take it at 720.
Broken today, my
Is it not proper?
OS, Lead Acetate
These are also parts of the CT.
How is it written?
Test, Observation, Inference
That's all you need to write in CT.
You don't have to do much more than that.
Thank you for helping me.
Sir, reaction rate
depends on the concentration of the reactant
If you take strong acid, then
Will react quickly if you take a weak acid
He will react late, that's all.
depends on the concentration of reactants

If acet is given, it will become a high concentration acet.
low, low, low, absolutely low
Alright, you'll be given plenty of concentrated acetic acid then.
You will be given pH paper, and you will also be given a pH solution.
To add, meaning to take a small amount and add it to it
If you are given a color
Look, regarding the range of Aceit, you know
You would know, the pH range of the phenolphthalein indicator is
It goes from 1 to 14 written, so there is color there
Therefore, one came, very solid
It turns red, it turns orange, it turns pink
You will read from 1 to 14, reading, reading, reading, reading, reading
Then the color will be obtained there.
So, I won't give you that solution.
Acidophilic dengue
The year is 2024.
But the one on the branch will give the big fruit.
When blue comes, 10 will come.
When green comes, 7 also arrives
We come by doing this.
You will be sent a PH friend request.
1 to 14 for the day
And from 1 to 14, I am different—different colors.
The color that comes in this tube, the liquid you'll be given, let me know its shade. Please tell me the exact shade of the liquid. Then, take the sample provided to you and compare it. Whatever color comes, understand that it's for this purpose.
What are you staying for from Basiqa, what are you waiting for, what are you keeping for yourself, who has collected what for the sake of the divine, who has a good understanding?
What should I do if I want to make this from that material?
Right?
Let me tell you a little about this.
No, just a little bit of hesitation, these children are a bit shy.
The doubt is, the BRSE's child I have
Starting tomorrow, you will be doing something most important for B.R.

Vaccination
So that you go there, so that I can accept you, so that I can clear whatever doubts you may have
If you had worked hard to clear the first tier, your second tier should have been cleared by my standards, the practical smear exam.
The practical exam is coming up, so also go through the important questions in chemistry—I'll try this one first, it'll be easier. Please make some videos; if you could just go through them once, sir, for the 12th science syllabus.
Yes, mango, 11, Pretishan, Saltanelsal, Group, and Anaisester, Ukkhean
I'll make a playlist for you, okay? Just write BRC there, okay? BRC is the pre-technical.
I'll just upload the BRC file as is, and in the Playlis, I'll put everything together—whatever the fault, whatever the physics practical—just put it all there, and you'll see for yourself, it's perfect.
I am a physics practical teacher. The practical questions come from the AC practical, and marks are awarded based on the practical.
As mentioned in the practicals, BRC
Okay
I'll make a video for this too.
You will come for offline, sir B R C

Tell me about the entrance in chemistry.
Bijou Tattarish and Salt Achiiko
This video is fine, thank you very much for your kindness.
Sir, you are very kind. We truly appreciate your kindness, Sir.
I have done basic and I have done C in organic chemistry masters course
If you just fill in the CT scan properly, there was hope for the experiment.
Yes, hey, what do you mean by saying that? What do you want to say, you meant something like that.
Your papers will be submitted, of course.
Write it down and have it checked
I want you to my videos
Look very carefully
And you will find out about the things
He told me, but
Come to Telegram
I'm telling you.
Karan Singh
Tell me the trick to pass the exam, sir.
How's the base, bro?
Look here
I'll tell you a really great thing.
If you have Salt Enlaces
I've watched your videos.
I'll fix it, you'll pass.
If you've taken the money anyway
And today's session, you know
What I told you today must be there.
If you're late to the lab today
Who will go to the video room
Don't look at my cup after that
After reading the chief's letter, you still have objections?
Passed the present exam
If you study seriously, you will definitely pass.
Because you've cleared the first test, right, brother?
What's up?
Sir, please
You've become so weak, man. Who are these people, Prasanth?
Alright
And for any children earlier for chemistry
If you have any doubts, please let me know, I'm here to help.
And
Even if not, I'll still make a small lip sync right here.
If you have any doubts, please feel free to ask me.
I was in eleventh grade, sir.

They went away
Gatooor today
Today, I've brought you this wild horse so your evening can go well.
They are the ones
The negatives in Saltvolatileus
Those who are negative are often very aged.
Start there tactically.
Should I show it, or just write "area"?
No, it's not about showing; it means what you're getting.
What? What are you getting from that? Meaning this stream?
Yes, I will definitely stream it because I've shared quite a few important things in it.
What is very important for BRCs for children
So if I don't stream this, it'll go to waste.
So, BRC, does any child have any doubt, or is there any question from any child that I haven't taken?
So many children were coming, two by two, three by three, some were watching, and then they just left without asking anything.
Maybe they already know all these things, but I've tried my best. Please do leave a comment in the comment box below—I'd really appreciate your feedback and motivation to create more videos for you.
Dude, my actual subscriber, so how many iPhones should I buy and hand out? Eleven Physics Activity Number Eight—I've already entered it, dude. I keep checking repeatedly to make sure I've entered it correctly.
I'm doing it for you, sir, to make him a priority, please reply, sir. I told you, didn't I? I'll handle it for you. It's fine, sir. Just give me a little time, sir. I'm speaking from teaching, sir. Paul's, sir.
It's not clear how they are playing; however, Bendl's tem analytic control is taking over.
They were also very skilled in sports, which is well-known, and even more so in wrestling.
You'll just be doing the key things because I'll be coming for physics tomorrow, okay?
Okay
