Two saturated aqueous solutions are prepared at 25 ºC.
Solution 1 is made by dissolving cadmium fluoride (CdF2, Ksp = 6.44 x 10-3) in 100.0 mL of water until excess solid is present. Solution 2 is prepared by dissolving lithium fluoride (LiF, Ksp = 1.84 x 10-3) in 200.0 mL of water until excess solid is present. Which solution has a higher fluoride ion concentration?
Again, two saturated aqueous solutions are prepared at 25 ºC.
One is made by dissolving lithium carbonate (Ksp = 8.15 x 10-4) in 100.0 mL of water until excess solid is present, while the other is prepared by dissolving lithium phosphate (Ksp = 2.37 x 10-4) in 200.0 mL of water until excess solid is present. Which solution has a higher lithium cation concentration?
