A Solution Containing CaCl₂ Is Mixed with a Solution of Li₂C₂O₄

question 55

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? K_sp (CaC₂O₄) = 2.3 × 10^-9.

• A)A precipitate will form since Q > K_sp 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 K_sp > Q for all possible precipitants.
• E)There is not enough information to determine the answer.
