phenolphthaleinendpoint
Phenolphthaleinendpoint is a term used in analytical chemistry to denote the endpoint of an acid–base titration as indicated by the phenolphthalein indicator. It is not a distinct chemical compound or process itself, but rather a descriptor for the stage at which phenolphthalein changes color and is judged to have signaled completion of the reaction.
Phenolphthalein is a triphenylmethane-type pH indicator. In acidic solutions it is essentially colorless, and as the
In practice, the phenolphthaleinendpoint is well suited for titrations where the equivalence point lies above pH
