The p in PH represents German Potenz ’power’ + H the symbol for hydrogen thus PH being derived from the reciprocal of the hydrogen –ion concentration. Chemistry is a subject that addresses PH in detail here it is a figure expressing acidity or alkalinity on a logarithmic scale on which 7 is neutral, lower values are more acidic, and higher ones more alkaline. In testing procedures acid turns litmus paper red whereas alkali turns litmus paper blue. Examples of acidic substances are citrus fruits like lemon, orange, even lactic acid, those of alkali are rock minerals like limestone or caustic soda, sodium, potassium, calcium.
