Titration Calculator
Calculate unknown solution concentration from a titration's volume and molarity.
Assumptions used in this calculation
- 1:1 stoichiometry: Assumes a 1:1 mole ratio between titrant and analyte, adjust the result manually for reactions with a different stoichiometric ratio.
About this calculator
Working out an unknown solution's concentration from a titration means applying the M₁V₁ = M₂V₂ relationship at the exact volume where the indicator changes color, the equivalence point, and a small error in reading the burette or in the algebra can shift the result noticeably, especially for dilute analytes where the calculated concentration is sensitive to volume precision. This calculator takes the titrant's known molarity, the volume of titrant dispensed to reach the equivalence point, and the analyte's sample volume, then solves M₁V₁ = M₂V₂ for the analyte's molarity, assuming a straightforward 1:1 mole ratio between the two reagents. It's built for chemistry students working through acid-base titration lab reports, or anyone standardizing a solution against a known titrant, letting you check a result quickly instead of rearranging and solving the equation by hand for every trial.
Worked example
0.1 mol/L titrant, 25mL used, 20mL analyte
Result: 0.125 mol/L
