Sodium carbonate, Na2CO3, is added dropwise to a solution that contains 1.0 X 10-2 M Ag+ and 5.0 X 10-2 M Cd2+. Specify the minimum molar concentrations of carbonate ion needed to precipitate each cation. (Ksp = 8.1 X 10-12 for Ag2CO3; Ksp = 1.8 X 10-14 for CaCO3)
If the same mass of Na2SO4 (MW: 142 g/mol) and K2SO4 (MW: 174 g/mol) were weighed and used for the gravimetry experiment, which will yield a greater amount of precipitate? Assume that the experiment was done correctly. • Indeterminate, it will depend on the amount of BaCl2 used. • They will yield the same amount of precipitate because the same mass was initially weighed. • K2SO4 because it has a larger molecular weight.

You look at the solubility of Ca(OH)2 in water (Ksp = 4 x 10–10). You wait until the system reaches equilibrium and then add Cr(C2H3O2)3. (Ksp = 6.7 x 10–31 for Cr(OH)3). Would affect do you think would occur to the solubility? (increase, decrease, stay the same) Show this through a calculation (Note: Two equilibria must be considered).
