A Solution Containing CaCl₂ Is Mixed with a Solution of Li₂C₂O₄

Multiple Choice

A solution containing CaCl₂ is mixed with a solution of Li₂C₂O₄ to form a solution that is 3.5 × 10^-4 M in calcium ion and 2.33 × 10^-4 M in oxalate ion.What will happen once these solutions are mixed? K_sp (CaC₂O₄) = 2.3 × 10^-9.

A) Nothing will happen since both calcium chloride and lithium oxalate are soluble compounds.
B) Nothing will happen K_sp > Q for all possible precipitants.
C) A precipitate will form as calcium oxalate is not soluble to any extent.
D) A precipitate will form since Q > K_sp for calcium oxalate.
E) There is not enough information to determine.
