    Phosphate of a metal M has the formula \[{{M}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}.\] The formula for its sulphate would be [CPMT 1973; MP PMT 1996]

    A)                 \[MS{{O}_{4}}\]               

    B)                 \[M{{\left( S{{O}_{4}} \right)}_{2}}\]

    C)                 \[{{M}_{2}}{{\left( S{{O}_{4}} \right)}_{3}}\]       

    D)                 \[{{M}_{3}}{{\left( S{{O}_{4}} \right)}_{2}}\]

    Correct Answer: A

    Solution :

                    \[{{M}_{3}}{{(P{{O}_{4}})}_{2}}\] means M is divalent so formula of its sulphate is \[MS{{O}_{4}}\].
