Nother metal phosphate is iron phosphate. it will behave similar to calcium phosphate in an acid solution. what is the net ionic equation including phases for fepo4(s) dissolving in h3o+(aq)? express your answer as a net ionic equation.

Iron phosphate when in acidic solution would dissociate into ions namely the iron ions and the phosphate ions. Furthermore, the phosphate ion would react to the hydronium ions forming HPO4^2-. To determine the net ionic equation we do as follows:

FePO4 <> Fe3+ + (PO4)3-
(PO4)3- + H3O+ <>  HPO4^2- + H2O

Adding the two equations would yield to:

FePO4(s) + H3O+(aq) ⇌ Fe^3+(aq) + HPO4^2−(aq) + H2O(l)
