9. Among the solubility rules previously discussed is the statement: All chlorides are soluble except Hg2Cl2, AgCl, PbCl2, and CuCl. (a) Write the expression for the equilibrium constant for the reaction represented by the equation AgCl(s)⇌Ag+(aq)+Cl−(aq). Is Kc > 1, < 1, or ≈ 1? Explain your answer. (b) Write the expression for the equilibrium constant for the reaction represented by the equation Pb2+(aq)+2Cl−(aq)⇌PbCl2(s). Is Kc > 1, < 1, or ≈ 1? Explain your answer. 10. Among the solubility rules previously discussed is the statement: Carbonates, phosphates, borates, and arsenates—except those of the ammonium ion and the alkali metals—are insoluble. (a) Write the expression for the equilibrium constant for the reaction represented by the equation CaCO3(s)⇌Ca2+(aq)+CO32−(aq). Is Kc > 1, < 1, or ≈ 1? Explain your answer. (b) Write the expression for the equilibrium constant for the reaction represented by the equation 3Ba2+(aq)+2PO43−(aq)⇌Ba3(PO4)2(s). Is Kc > 1, < 1, or ≈ 1? Explain your answer.
