What is the formula for an acid-base titration?

Question

I titrated acetic acid with NaOH and have the volume and concentration of NaOH and need to solve for the concentration of acetic acid.. what formula I should use? Is it M1V1=M2V2?

Answer 1

Nope, that formula's kinda incomplete.

MaVa = MbVb * ratio a/b

or MbVb = MaVa * ratio b/a

The stoichiometric ratio is very important in titrations.

Answer 2

Yes, use that formula, but make sure that all the volumes are in litres. Divide ml (or cm3) by 1,000 to get litres.
