As we know,

                     pH + pOH  =  14
Or,
                     pOH  =  14 - pH

Putting Value of pH,

                    pOH  =  14 - 10.62

                    pOH  =  3.38

pOH is converted into [OH⁻] as follow,

                   [OH⁻]  =  10⁻pOH             ∴ -pOH is in power, 10 means antilog

                   [OH⁻]  =  10⁻³°³⁸

                   [OH⁻]  =  0.0004168

                   [OH⁻]  =  4.16 × 10⁻⁴
