The pH of a solution is a measure of hydrogen (H+) ion concentration, which is, in turn, a measure of acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions: (5.16) See also Shows Like Claws? WebbA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base how many cm is 57
