What is Titration, equivalence?

Also known as: titration · analyte · titrant · equivalence · equivalence point · end point

Definition 15.1 University Chemistry — Year 1 · Chapter 15 — Titration Methods and Curves

A titration determines the amount of a species, the analyte, by a reaction with a reagent of known concentration, the titrant, added progressively. The reaction must be single, quantitative (KK large) and fast. The equivalence is reached when titrant and analyte have been brought together in the stoichiometric proportions of the reaction; the volume added then is the equivalence volume, and the point of the titration curve at that volume is the equivalence point. The volume at which the experimenter stops, seeing a colour change or a break in a curve, is the end point; a good method makes it coincide with the equivalence.
