Titration Equivalence Calculator — MₐVₐ = M_bV_b

At the equivalence point, moles of acid equal moles of base (for 1:1 stoichiometry). With three of the four values — two concentrations and two volumes — the fourth drops out of MₐVₐ = M_bV_b.

How to interpret the result

Worked check: 25.00 mL of 0.100 M HCl titrated with 0.100 M NaOH → V_b = 0.100 × 25.00 / 0.100 = 25.00 mL. Equal concentrations neutralize equal volumes.

Assumptions

• 1:1 acid–base stoichiometry (monoprotic acid, monobasic base)
• Reaction goes to completion
