    The sulphate of a metal has the formula \[{{M}_{2}}{{\left( S{{O}_{4}} \right)}_{3}}.\] The formula for its phosphate will be  [DPMT 1982; CPMT 1972; MP PMT 1995]

    A)                 \[M{{\left( HP{{O}_{4}} \right)}_{2}}\]   

    B)                 \[{{M}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}\]

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

    D)                 \[MP{{O}_{4}}\]

    Correct Answer: D

    Solution :

                    Yet the formula of sulphate of a metal (M) is \[{{M}_{2}}{{(S{{O}_{4}})}_{3}}\], it is \[{{M}^{3+}}\] ion so formula of its phosphate would be \[MP{{O}_{4}}\].
