The concentration of the hydroxide ion in a solution with pH 4.282 would be 1.91 x [tex]10^{-10}[/tex] M

Recall that:

pH + pOH = 14

Thus, with a pH of 4.282;

pOH = 14 - 4.282

          = 9.718

Also recall that:

pOH = -log10 [OH]

         9.518 = -log10 [OH]

             [OH] = 10^-9.518

                       = 1.91 x [tex]10^{-10}[/tex] M
