Titration Calculator

Find an unknown analyte concentration from a titrant concentration, equivalence volume, aliquot volume, and balanced mole ratio.

In-browser processingNo account requiredPrivacy details ↗

Use positive values from 1e-12 to 1e6; coefficients must be integers from 1 to 100.

Assumes complete stoichiometric reaction at equivalence, with matching volume units. You supply the balanced ratio and equivalence point. This does not infer reaction chemistry, endpoint error, or experimental safety.

Enter the values, then calculate.

Unknown concentration = titrant concentration × titrant volume ÷ aliquot volume × analyte coefficient ÷ titrant coefficient.

A QUICK WALKTHROUGH

How to use this tool

  1. Enter titrant molarity and volume at equivalence.
  2. Enter the analyte aliquot volume and the two coefficients from your balanced reaction.
  3. Calculate the unknown molarity.

Calculation

Unknown concentration = titrant concentration × titrant volume ÷ aliquot volume × analyte coefficient ÷ titrant coefficient.
