A. pH = 2.52

POH   = 14-PH

          = 14-2.52

POH     = 11.48

-log[OH^-] = 11.48

     [OH^-]    = 10^-11.48   = 3.3*10^-12M

B. pH = 8.09

POH = 14-PH

          = 14-8.09

POH     = 5.91

-log[OH^-] = 5.91

     [OH^-]   = 10^-5.91

                      = 1.23*10^-6M

C. pH = 13.58

POH   = 14-PH

            = 14-13.58

              = 0.42

-log[OH^-] = 0.42

       [OH^-]   = 10^-0.42

                   = 0.38M
