  • question_answer Which hydroxide will have lowest value of solubility product at normal  temperature \[({{25}^{o}}C)\]    [IIT 1990; RPMT 1997]

    A)                 \[Mg\,{{(OH)}_{2}}\]     

    B)                 \[Ca\,{{(OH)}_{2}}\]

    C)                 \[Ba\,{{(OH)}_{2}}\]       

    D)                 \[Be\,{{(OH)}_{2}}\]

    Correct Answer: D

    Solution :

                    \[Be{{(OH)}_{2}}\]has lowest solubility and hence lowest solubility product.
