    \[Mg{{(OH)}_{2}}\] is a weaker base than NaOH.

    Answer:

                    The ionisation enthalpy of Na is less compared to that of Mg. Therefore, M-O bond in NaOH can cleave more easily than in\[Mg{{(OH)}_{2}}\]. In other words, NaOH can release \[O{{H}^{-}}\] ions in solution more readily as compared to \[Mg{{(OH)}_{2}}\]. It is therefore, a stronger base.
