Question

A volume of 25 ml of H2CrO4 is titrated to an end point using 5.37ml of .5 N NaOH. assuming complete neutralization, calculate the molarity of HCl

Answer 1

You mean H2CrO4, probably?

Answer 2

yes sorry.

Answer 3

Well, write down the chemical equation for the neutralisation reaction first.

Answer 4

I'm at a complete loss here. I have no idea what I'm doing.

Answer 5

Hoss, Vincent is right. You start with the balanced chemical equation. Then convert the quantities to moles. Set up the stoichiometry and then calculate. Do you know how to write the balanced equation?

Answer 6

Which substance is the acid, which substance is the base?

In your case, a H+ from the acid will react with a OH- from the base to form water;

Look up neutralisation reaction in your textbook.
