Question

Another metal phosphate is cobalt phosphate. It will behave similar to calcium phosphate in an acid solution. What is the net ionic equation including phases for CoPO4(s) dissolving in H3O^+(aq)?

Answer 1

We are given with
Cobalt phosphate - CoPO4

We are asked for the net ionic equation for the phosphate dissolving in H3O+

The net ionic equation is
CoPO4 (s) + H3O+ (aq) ----->  HPO42- (aq) + Co3+ (aq) + H2O *(l)

Answer 2

Answer: The equation is given below.

Explanation:

Calcium phosphate does not dissolve in water but in acid it does.Similarly cobalt phosphate is also soluble in acidic solution as it get dispersed in the acid solution.

$CoPO_4(s)+H_3O^(aq)+\rightarrow HPO_{4}^{2-}(aq)+Co^{3+}(aq)+H_2O(l)$

When cobalt phosphate dissolves in acidic solution as it get strongly attracted by the acid molecules and dissociates into cobalt(III) ions, hydrogen phosphate and water molecule.

Hence, the net ionic equation for cobalt phosphate in hydronium ion is given above.
