Quick answer
C1V1 = C2V2 (adjusted for reaction stoichiometry).
MaVa = MbVb (1:1 stoichiometry)
How to use the Titration Calculator
- 1Enter the known concentration of your titrant.
- 2Enter the volume of titrant used to reach the equivalence point (from the burette).
- 3Enter the sample volume to find its unknown concentration.

Frequently asked questions
What if stoichiometry isn't 1:1?
Multiply or divide the result by the mole ratio between acid and base from the balanced equation.
Why does the endpoint matter?
The indicator's colour change should closely match the true equivalence point for an accurate result.
