Quick answer

At the equivalence point, moles of titrant equal moles of analyte adjusted for stoichiometry.

The formula

Ca = (Cb × Vb × a) ÷ (Va × b)

Frequently asked questions

What if the ratio isn't 1:1?

For H2SO4 versus NaOH use 0.5 — check the balanced equation.

Why repeat titrations?

Concordant titres within 0.1 mL confirm the endpoint is reliable.
