Solution.

pH+pOH=14;pH+pOH =14;

pH=lg[H3O+];pH = -lg[H_3O^{+}];

pOH=[OH];pOH = -[OH^{-}];

pH=lg[0.0325]=1.49;pH = -lg[0.0325] = 1.49;

1.49+pOH=14;1.49+pOH = 14;

pOH=12.51;pOH = 12.51;

pOH=lg[OH];pOH = -lg[OH^{-}];

10POH10^{-POH} = [OH];[OH^{-}];

1012.51=10^{-12.51} = [OH];[OH^{-}];

[OH]=3.091013[OH^{-}] = 3.09\sdot10^{-13} mol/L;mol/L;

Answer: [OH]=3.091013;[OH^{-}] = 3.09\sdot10^{-13};
