Question

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

Answer 1

Answer:

$\boxed {\boxed {\sf Almost \ all \ phosphates \ are \ insoluble}}$

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.

• All phosphates are insoluble except Na₃PO4 (sodium phosphate), K₃PO4 (potassium phosphate), and H₁₂N₃PO₄ (ammonium phosphate).

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

Answer 2

Answer:

Basically, all phosphates except Sodium phosphates, Potassium phosphates and Ammonium phosphates are insoluble in water. That, of course, includes Magnesium phosphate.
