Definition & Formula
pH & pOH, often denoted by an alphabet H+ & OH- respectively, is the measure of hydrogen & hydroxide ion concentration of the solution. pH is an important factor in chemical process, represents the acid & alkalin level of a solution. Whereas, pOH values are derived from pH values to represent hydroxide ion concentration of the solution.
