Question

Does a reaction occur when aqueous solutions of chromium(III) sulfate and zinc acetate are combined?

Does a reaction occur when aqueous solutions of chromium(III) sulfate and silver(I) acetate are combined?

If a reaction does occur, write the net ionic equation.

Answer 1

1.

Cr₂(SO₄)₃ (aq) + 3 Zn(CH₃COO)₂ (aq)

2 Cr(CH₃COO)₃ (aq)  + 3 ZnSO₄ (aq) .

All are soluble in water , hence no reaction occurs.

2.

Cr₂(SO₄)₃ (aq)  + 6 CH₃COOAg (aq)  

3 Ag₂SO₄ (s) + 2 Cr(CH₃COO)₃ (aq)

Net ionic reaction is

6 Ag⁺ (aq) + 3 SO₄^2- (aq)   3 Ag₂SO₄ (s) .
