Sir can you told me if molecular wt of edta is 292gm.then how much I take qty. for 1m solution.
Sir i want ask abt complexometry it's stability and factors affecting stability and titration curves
EDTA standardize by Calcium carbonate primary solution calculations and method ?
thank you sir .. this is very useful video for me
Sakthi Dharshni
Thank you.
Please watch latest videos of other topics; share the channel link with your friends and help us to spread the knowledge.
sure sir
In edta can you explain the molarity calculation
Thank you sir.

Welcome!!!!!!!

Sir, very well explained. but for the molarity of Na2 EDTA the simple formula is m = wt. of granulated zinc in gm divided by milliequivalent of Zn (ie 0.0654) divided by volume of EDTA into dilution factor. [m=w/0.0654*v*10]
Sharad Agrawal You can calculate in that way also.
Sharad Agrawal Thank you

For molarity of calcium carbonate
What it will be in terms of calcium carbonate
How can we prepare buffer
Sir, 1000 ml 1(N) edta =372.24 g.
And for edta 1(N)=2(M)
So 1000 ml 2(M) edta =372.24 g
1000 ml 1(M) edta = 372.24÷2 =186.12 g
But how is it 372.24 g for 1000 ml 1(M) edta solution ? Sir, please solve my doubt.
great sir je
Thank You.
SIR , I want to know how to prepar iron solution for titration (0.000580M)
deepak kumar
It may be Iron salt, because how you will dissolve iron?
Sir, i want 56m of EDATA solution.....!
How to prepare bromine water.and is it required freshly prepared

Sir we want estimation of calcium from calcium gluconate and magnesium from magnesium sulphate
Sab padha denge App me Course Join kar lo. Search "Dr. PK Classes" in Google Playstore or see my community tab. Course me Diwali Offer bhi chal rha hai.
And Free book bhi milega aapko apne address par.
Sir if we preserve the buffer the pH doesn't vary
Sadiya Khanam It may vary depending on the conditions, so always try to prepare fresh
Thank you sir
Sir, is EDTA Standardization step really necessary before titration? Thank you sir.
Ideally you have to perform. But you can directly perform titration if weighing is perfectly done.
@@pkclasses100 Thank you sir 👍👍
How prepare 6 % edta fe from edta Na
Take 6g and dissolve in distilled water and make up.the volume up to 100mL. It will be 6% w/v
EDTA Na +Fe SO4_____ EDTA Fe
The question how gets 6% of products
W/w
W/v
You look nervous sir. I understood tho. Thank you
This playlist was my very first videos, please have a look to our latest videos.
Sir hindi me
Sir I have a question to solve.Could you comment me the email.

it looks like you are reading from a book.
i dont like the way you explain
no logic in calculation and no proper explanation for the calculation
Thanks a lot for the feedback. This was my first video series. Please watch my latest uploads. If you still dislike, give your suggestions or you have option not to watch my videos; and go through another channel.
Dr. Puspendra Classes the point is,you need to be interactive about your lecture and it shouldn't look like a bookish language.
That's what must be kept while lecturing
Thanks... You have the liberty to watch alternative videos.
@@pkclasses100 sir don't get offended plz.
He is not trying to do so....actually I can sense
@@lokpriyashukla7721 Do you perceive it as constructive criticism then?
it looks like you are reading from a book.
(Ok so what to do?)
i dont like the way you explain
(Then watch others videos why say it this way )
no logic in calculation and no proper explanation for the calculation(Ok it means you knew much better and just camehere to give him rating?)
Now can you understand ?
