pH is a measure of the concentration of OH− ions in a solution of an acid or base. The pH scale plots the concentration of solutions in a range from 0–16.
pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots the concentration of solutions in a range from 0–14.
