Another metal phosphate is aluminum phosphate. It will behave similar to calcium phosphate in an acid solution. What is the net ionic equation including phases for AlPO4(s) dissolving in H3O+(aq)? Assume that metal phosphate and hydronium cations react reversibly in a 1:1 ratio.

Respuesta :

Answer:

AlPO4(s) + H3O+(aq) --------------> Al3+(aq) + HPO4^2-(aq) + H2O(l)

Explanation:

The net ionic equation for the reaction between aluminum phosphate and hydronium ion shown below.

AlPO4(s) + H3O+(aq) --------------> Al3+(aq) + HPO4^2-(aq) + H2O(l)

Note H3O+(aq) comes from an acid. The acid is required to keep the Al3+(aq) in aqueous solution. If not, it will precipitate as Al(OH)3.
