WebLe potentiel hydrogène, noté pH, est une mesure de l' activité chimique des protons ou ions hydrogène note 1 en solution. Notamment, en solution aqueuse, ces ions sont présents sous forme d' ions hydronium (ion H + hydraté, ou H 3 O + ). Le pH sert à mesurer l’acidité ou la basicité d’une solution.

Did you know?
De HSAB-theorie (Engels: Hard Soft Acid Base Theory), ook bekend als het Pearson zuur-baseconcept, wordt in de chemie gebruikt als de verklaring van de (in)stabiliteit van verbindingen, complexen, en de (on)mogelijkheden van reactiepaden. Met de begrippen hard, zacht, zuur en base worden basiseigenschappen van (chemische) deeltjes beschreven: • Hard verwijst naar kleine, hooggeladen deeltjes en die slecht gepolariseerd kunnen worden. WebThe HSAB concept is an acronym for 'hard and soft acids and bases '. Also known as the Pearson acid base concept, HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.
