What Happens When Nickel II Phosphate Reacts With Acids?

When nickel II phosphate (Ni3(PO4)2) reacts with acids, it undergoes acid-base reactions, resulting in the formation of soluble nickel salts and phosphoric acid. The specific reaction will depend on the type of acid used.

For example, when reacted with hydrochloric acid (HCl), the following reaction occurs:

Ni3(PO4)2 + 6HCl → 2NiCl2 + 2H3PO4 + 3H2O

Similarly, when reacted with sulfuric acid (H2SO4), the following reaction occurs:

Ni3(PO4)2 + 6H2SO4 → 3NiSO4 + 2H3PO4 + 4H2O

In both cases, the nickel phosphate compound is converted into a soluble nickel salt (NiCl2 or NiSO4) and phosphoric acid (H3PO4) is formed as a product. The reaction may also produce water molecules.
