1 litre of a 4.0 × 105 mol L¯1 aqueous solution of CoCl₂ (cobalt chloride) is mixed with 1 litre of a 9.0 x 106 mol L-1 aqueous solution of Na2CO3 (sodium carbonate). What will be observed once these solutions are thoroughly mixed? (Ksp(COCO3) = 1.0 × 10-10) a. The solution becomes cloudy since Q > Ksp for cobalt carbonate. O b. Nothing is observed after mixing since Q < Ksp for cobalt carbonate. OC. The concentrations of CoCl₂ and Na₂CO3 are both higher than the Ksp so a precipitate of cobalt carbonate will instantly be observed. Ⓒd. Nothing is observed after mixing since Q = Ksp for cobalt carbonate.
