Question

Complete and balance the precipitation reactions. Include physical states. Refer to the solubility rules as necessary. precipitation reaction: Ba(NO3)2(aq)+CuSO4(aq)⟶BaSO4+CU(NO3)2 Ba ( NO 3 ) 2 ( aq ) + CuSO 4 ( aq ) ⟶ BaSO 4 + CU ( NO 3 ) 2 precipitation reaction: K3PO4(aq)+MgCl2(aq)⟶6KCl(aq)+Mg3(PO4)2(s) K 3 PO 4 ( aq ) + MgCl 2 ( aq ) ⟶ 6 KCl ( aq ) + Mg 3 ( PO 4 ) 2 ( s )

Answer 1

Answer:

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)₂
• The 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.
