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]

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

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

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

Phosphate of a metal M has the formula \[{{M}_{3}}{{\left( P{{O}_{4}}
