WebThe pH of a solution to be examined is rel ated to that of a reference solution (pHS) by the following equation: pH = pHs - (E-ES)/k in which E is the potential, expressed in volts, of the cell containing the solution to be examined and E is the potential, expressed in volts, of the cell containi ng the solution of known pH (pH S) Table 2.2.3.-1. The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration. See more In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
