Hi!!
I have a problem... this is the method of Ph.Eu. for Standardization of Acid Sulfuric 0.5 M (1 N):




could you tell me what is the correct formula?

My ideas i:

Factor Correction =       (Weight NA2CO3 * 1) / (53 x ml)

There is nothing wrong with the factor you've written.  You have said in math language, what was written in words.

Now what.

Will that formula, written by you, match what you have to perform?

But.... my result is about 9 ml instead 18 ml!!!!

Did you consider that sulfuric acid has two ionizable protons?

Ok but.... 1 ml is = to 53 mg... so 1000 mg is = ?

1:53=x:1000

Right??
