WebThe numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)). For example, if a solution has a H+ concentration of 10 -3 M, the pH of the solution will be -log (10 -3 ), which equals 3. WebDer pH-Wert (Abkürzung für Potential des Wasserstoffs, lat. pondus hydrogenii oder potentia hydrogenii) ist ein Maß für den sauren oder basischen Charakter einer wässrigen Lösung. Er ist die Gegenzahl des dekadischen Logarithmus (Zehnerlogarithmus) der Wasserstoffionen - Aktivität [1] und eine Größe der Dimension Zahl.
