Eine pH-Pufferlösung ist eine Lösung, die dazu dient, den pH-Wert einer Probe konstant zu halten. Sie besteht aus einer schwachen Säure und ihrer korrespondierenden Base, die in einer bestimmten Konzentration gemischt werden, um einen pH-Wert zu erreichen, der in der Regel bei Raumtemperatur stabil bleibt.

Ein Puffer kann als eine Art "Stabilisator" für den pH-Wert einer Lösung betrachtet werden. Wenn eine saure oder alkalisch Substanz in eine Pufferlösung gegeben wird, reagiert der Puffer mit dieser Substanz, um den pH-Wert zu stabilisieren und innerhalb eines bestimmten Bereichs zu halten. 

Pufferlösungen werden oft in der Wasseranalyse eingesetzt, um den pH-Wert einer Probe zu stabilisieren und somit genau und reproduzierbare Messergebnisse zu erzielen.

Pufferlösungen sollten vor Licht und Feuchtigkeit geschützt gelagert werden, um ihre Wirksamkeit und Genauigkeit zu gewährleisten.
