equivalence point

The equivalence point is a key moment in a chemical reaction, particularly during titration, where the amount of one substance completely reacts with an equivalent amount of another. For example, if you’re mixing an acid with a base, the equivalence point is reached when the acid has been entirely neutralized by the base. At this stage, there is no excess of either substance, indicating that the reaction is complete. This point is typically identified using indicators or by measuring changes in properties like pH, helping scientists understand the concentrations of the reactants involved.
