How to Use Titration Calculator
Choose whether you want to find an unknown concentration or the required titrant volume. For unknown concentration mode, enter sample volume, titrant concentration, titrant volume, and the reaction coefficients. For volume mode, also enter the known sample concentration.
Keep volume units consistent. The calculator labels volumes as milliliters and concentrations as mol/L, which matches common laboratory titration notes. Coefficients should come from the balanced neutralization equation, not from the names of the acid and base alone.
Review the mole rows after calculating. They show whether the amount of titrant and the stoichiometric ratio produce a plausible concentration or volume.
Formula & Theory - Titration Calculator
The Titration Calculator extends C1V1 = C2V2 with stoichiometry. For a reaction where analyte coefficient a reacts with titrant coefficient b, the mole relationship is analyte moles divided by a equals titrant moles divided by b.
For unknown concentration, the calculator rearranges that relationship using titrant concentration and titrant volume. For required volume, it starts from known sample concentration and sample volume, then solves for the titrant volume needed to meet the same mole ratio. This handles common monoprotic and multiprotic acid-base examples as long as the coefficients are entered correctly.
