A) \[{{M}_{2}}P{{O}_{4}}\]
B) \[{{M}_{3}}{{\left( P{{O}_{4}} \right)}_{2}}\]
C) \[{{M}_{2}}{{\left( P{{O}_{4}} \right)}_{3}}\]
D) \[MP{{O}_{4}}\]
Correct Answer: B
Solution :
Since the chloride of a metal is \[MC{{l}_{2}}\] therefore metal ?M? must be divalent i.e. \[{{M}^{2+}}\]. As a result the formula of its phosphate is \[{{M}_{3}}{{(P{{O}_{4}})}_{2}}\].
