Quiz 6 Name: Chem 1B, Spring 10 Fossum 1. a. (5) Calculate the solubility of Ag 2 SO 4 (in g/L) in the presence of 0.20 M Na 2 SO 4 (aq) . K sp for Ag 2 SO 4 = 1.5 × 10 -5 . b. (1.5) Will this solid (in part a) be more soluble, less soluble, or equally soluble when dissolved in pure water? Why? Explain. c. (1.5) Will this solid (in part a) be more soluble, less soluble, or equally soluble in the presence of acid? Why? Explain.
