1. Calculate the molar solubility of bbarium sulfate, BaSO4, in 0.010 M Sodium Sulfate, Na2SO4, solution at 25C. Compare this to the solubility of BaSO4 in pure H2O. What is the common ion?
2. We mix 100 mL of 0.010 M Potassium Sulfate, K2SO4, and 100 mL of 0.10 M lead (II) nitrate, Pb(NO3)2, solutions. WIll a precipitate form?
