d. Consider the dissolution of PbCl2 in water. i) How does the solubility of lead chloride would be affected by the addition of 1M NaCl. ii) Would you expect the addition of 1M KNO3– to have an impact on the solubility of lead chloride? Why? e. For the following chemical reaction A + B?C, the equilibrium constant is 4.34x10-4. Will this reaction favor the products or the reactants? If the reaction quotient is measured to be 9.87, in which direction will the reaction proceed? (forward or backward)
