When has a titration reached its equivalence point?

A titration reaches its equivalence point when the amount of titrant added is stoichiometrically equivalent to the amount of analyte in the solution, meaning that the reactants have completely reacted with each other according to the balanced chemical equation. This point is typically indicated by a significant change in a measurable property, such as pH, which can be observed using an appropriate indicator or pH meter. At this stage, the concentration of the titrant and analyte are equal, allowing for accurate calculations of concentration.
