I’m an H⁺ denier, in that I refuse to consider loose protons to be real hydrogen, so I personally believe it stands for ‘pretend’.

    They told me at school that ‘p’ meant ‘negative log’. So ‘pH’ means ‘the negative log of the concentration of Hydrogen ions in moles/litre’.

    pH 1 is 1 x 10-1 (strong acid)

    pH 7 is 1 x 10-7 (neutral)

    pH 14 is 1 x 10-14 (alkaline)

    (Chemistry was a long time ago, though)
