The reaction between copper(II) chloride (CuCl₂) and ammonium phosphate ((NH₄)₃PO₄) is a double displacement reaction that results in the formation of copper(II) phosphate (Cu₃(PO₄)₂) and ammonium chloride (NH₄Cl).

Here's the balanced chemical equation:

3CuCl₂(aq) + 2(NH₄)₃PO₄(aq) → Cu₃(PO₄)₂(s) + 6NH₄Cl(aq)

Here's a breakdown of the reaction:

* Copper(II) chloride (CuCl₂) is a soluble ionic compound.

* Ammonium phosphate ((NH₄)₃PO₄) is also a soluble ionic compound.

* Copper(II) phosphate (Cu₃(PO₄)₂) is an insoluble ionic compound, meaning it will precipitate out of solution as a solid.

* Ammonium chloride (NH₄Cl) is a soluble ionic compound and will remain in solution.

Key Observations:

* A blue-green precipitate (Cu₃(PO₄)₂) will form when the two solutions are mixed.

* This reaction is a precipitation reaction because an insoluble solid is formed.

Net Ionic Equation:

The net ionic equation only includes the ions that participate in the formation of the precipitate:
