What is an equivalence point?

An equivalence point is the point in a titration where the amount of titrant added is stoichiometrically equivalent to the amount of analyte being titrated. This point is indicated by a sharp change in the pH or color of the solution being titrated. At this point, the reaction between the titrant and analyte is complete, and the moles of titrant added can be used to determine the concentration of the analyte.
