Multiple Choice
A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is 2.1 × 10-5 mol L-1 in calcium ion and 4.75 × 10-5 mol L-1 in oxalate ion. What will happen once these solutions are mixed? Ksp (CaC2O4) = 2.3 × 10-9.
A) A precipitate will form since Q > Ksp for calcium oxalate.
B) Nothing will happen since both calcium chloride and lithium oxalate are soluble compounds.
C) Nothing will happen since calcium oxalate is extremely soluble.
D) Nothing will happen since Ksp > Q for all possible precipitants.
E) There is not enough information to determine the answer.
