Puttaneska , 23 days ago (edited 23 days ago) 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)
