Ph is negative logarithm of
WebbThe degree of acidity is expressed in terms of pH, which is defined as the negative logarithm of the hydrogen ion activity. Therefore, the pH of a 0.01-molar hydrogen ion solution is pH = −log ( 10−2 mol H+ L) = 2 pH = − log ( 10 − 2 mol H + L) = 2 At pH 7, the concentration of H+ ions and OH- ions are equal, and the soil or solution is neutral.
