pH Theory and Practice - 2 - Preface The importance of pH Many of nature's processes are highly dependent on pH. This is also the case for the chemical reactions which take place in industry or in a labo-ratory. In 1909, the founder of the modern pH concept, S.P.L. Sørensen, ... pH° = zero pH which is defined as the pH value at which the

The pH range of 0 to 14 accounts for hydronium activities from 10 to 1E-14 mol/litre. One mol of water weighs 18 gram. A pH=7 corresponds to hydronium activity of 1E-7 mol/litre (1E-7). Because log( 10-7) = -7, the pH scale leaves the minus sign out.
