A) \[{{M}_{2}}{{(P{{O}_{4}})}_{2}}\]
B) \[M(P{{O}_{4}})\]
C) \[{{M}_{2}}P{{O}_{4}}\]
D) \[{{M}_{3}}{{(P{{O}_{4}})}_{2}}\]
Correct Answer: D
Solution :
Valency of metal is +2 by formula MO so its phosphate would be \[{{M}_{3}}{{(P{{O}_{4}})}_{2}}\] because valency of \[\left[ P{{O}_{4}} \right]\] is -3.
