pH-Wert – Wikipedia

Werden Säuren in Wasser gelöst, geben diese durch die Dissoziation Wasserstoffionen an das Wasser ab, der pH-Wert der Lösung sinkt. Werden Basen gelöst, geben diese Hydroxidionen ab, die Wasserstoffionen aus der Dissoziation des Wassers binden. Sie können auch selbst Wasserstoffionen binden, wie es für Ammoniak → Ammonium gilt. Mithin erhöhen Basen den pH-Wert. Der pH-Wert ist ein Maß der Menge an Säuren und Basen in einer Lösung.
