A) 1 L of solution contains 0.10 mol Ag+ and 0.10 mol of Ba2+.If a highly concentrated solution of K2CrO4 is added drop by drop,which will precipitate first, Ag2CrO4 or BaCrO4?

Ksp for AgCrO4 = 2.0 x 10^-12; Ksp for BaCrO4= 1.2 x 10^-10

B) If the solution in part \"A\" contains 0.0010 Ag+ and 0.0010mol of Ba2+ instead, which will precipiate first, Ag2CrO4 orBaCrO4?
