Asolution 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? ksp (cac2o4) = 2.3 × 10-9. a. nothing will happen since both calcium chloride and lithium oxalate are soluble compounds. b. nothing will happen ksp> 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 > ksp for calcium
