The poh of a solution is equal to

WebbThe strategy here is to calculate the pOH and then, using the pH + pOH = 14 relationship, determine the pH. NaOH is a strong base, so [OH –] = [NaOH], and therefore, the pOH is: pOH = -log 0.850 = 0.0706 The pH then is equal to: pH = 14 – pOH = 14 – 0.0706 = 13.9 As expected, the pH is very high because it is a solution of a strong base.
