: a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity and on which each unit of change represents a tenfold change in acidity or alkalinity andthat is the negative logarithm of the effective hydrogen-ion concentration or hydrogen-ion activity in gram equivalents per liter of the solution −7, it is customary to say that the pH of pure water is 7 —Linus Pauling>; also : the conditionrepresented by such a number —compare PK
