Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)

2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)

Explanation:Precipitation reactions are types of reactions that involve a reaction between soluble salts to form an insoluble salt or a precipitate and a soluble salt.The equations given in the question are examples of precipitation reactions that lead to the formation of precipitates BaSO₄ and Mg₃(PO₄)₂The balanced equations are;

Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)

2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)

Based on solubility rules, all sulfates are soluble except CaSO₄, BaSO₄, PbSO₄ and silver sulfate. Therefore, BaSO₄ is a precipitate and will have a solid-state.All phosphates are insoluble except those of ammonium, potassium, and sodium. Therefore, Mg₃(PO₄)₂ is a precipitate and will have a soluble state.

A precipitation reaction is a reaction in which a mixture of aqueous reactants yields an insoluble product.

Aqueous solutions contains species that are soluble in water. Sometimes, a mixture of aqueous reactants yields a product that is insoluble in water. Such a product is called a precipitate and the reaction is a precipitation reaction.

The following are examples of balanced precipitation reactions;

Ba(NO3)2(aq) + CuSO4(aq)⟶ BaSO4(s) + Cu(NO3)22K3PO4(aq) + 3MgCl2(aq)⟶ 6KCl(aq) + Mg3(PO4)2(s)

In the first reaction, the precipitate formed is BaSO4 while in the second reaction, the precipitate formed is Mg3(PO4)2. According to the solubility rules, sulfates and phosphates of group 2 cations are insoluble in water.
