How Is Nickel (II) Phosphate Synthesized?

Nickel (II) phosphate can be synthesized through a precipitation reaction by mixing a solution of nickel sulfate and a solution of sodium phosphate in water. The resulting precipitate is washed with distilled water to remove any impurities and dried in an oven. The chemical equation for the reaction is:

NiSO4 + Na3PO4 → Ni3(PO4)2 + 3Na2SO4

It is important to carefully control the pH of the reaction mixture during the synthesis as pH affects the purity and crystallinity of the product. Additionally, the reaction should be carried out at a temperature between 50-80°C to ensure optimal yield.
