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)

You're missing a 4 in the alkaline line
