Enter the titrant concentration, the titrant volume used to reach the equivalence point, and the analyte volume. Optionally adjust the mole ratio for non-1:1 reactions. The calculator solves for the unknown analyte concentration.
About the Titration Calculator
Titration is a quantitative analytical technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. At the equivalence point, moles of acid equal moles of base (adjusted for stoichiometry), allowing you to calculate the unknown concentration.
Frequently Asked Questions
What is an equivalence point?
The equivalence point is the moment in a titration when the moles of titrant exactly equal the moles of analyte (adjusted for stoichiometry). At this point, the reaction is complete.
How does the mole ratio work?
For a 1:1 acid-base reaction (like HCl + NaOH), the ratio is 1. For H2SO4 + 2NaOH, enter 0.5 because each mole of acid reacts with 2 moles of base. The ratio adjusts the stoichiometry.
What if my titration is not 1:1?
Adjust the mole ratio input. For diprotic acids like H2SO4, one mole reacts with two moles of NaOH. Set the ratio accordingly to get the correct unknown concentration.
