Reply To:Definition of pH (SB-41) What's the pH?

Lösung:

In principle a concentration ('number of particles per volume'). H⁺ (or more specifically: H3O⁺ ) This number is in order of magnitude. 1 mol/l to 0.00000000000001 mol/l Moving is taking the Overview of the (negative tooth) logarithm, specifically: pH = -log(c[H₃O⁺]).
This gives a range of the pH's of -log1) = -log10⁰)= 0 up to – logs0.00000000000001) = log10^-14)= 14
