Answer:

Phosphate anion is a polyatomic ion with a formal charge of #-3#.

Explanation:

Phosphates are the salts of #"phosphoric acid, "H_3PO_4#, a mineral acid of moderate strength. Both biphosphates, salts of #HPO_4^(2-)#, and phosphates, #PO_4^(3-)#, tend to form insoluble salts with most metal ions save the alkali metals.
