OBS

DEF

Action de l'eau sur les ions correspondant à un sel dissous, qui tend à l'établissement d'un état d'équilibre où coexistent les ions et des molécules d'acide ou de base assurant la formation du sel. Les molécules d'acide ou de base peuvent inversement repasser à l'état d'ions, quand les conditions du milieu varient.

OBS

L'hydrolyse réversible s'observe particulièrement pour les sels d'acides organiques faibles à radicaux hydrophobes importants.
