Why would Magnesium Phosphate (Mg3(PO4)2) not make an aqueous solution?

Please help!

Explanation:

For magnesium phosphate to make an aqueous solution, it must be soluble in water.

Let's check the solubility rules. There are many different lists and versions, but it should mention a rule about phosphates.

Magnesium phosphate is included in "all phosphates" so it is insoluble and can't become an aqueous solution.

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
