Ksp of CaSO4 = 2.4 x 10-5, 100 mL of 0.01M CaCl2 is mixed with 100 mL of 0.02 M Na2SO4. Concentration of Ca2+ and So42- will become Half because volume becomes double.

Kip = [Ca2+] [SO42-]
= 0.005 x 0.01 = 5 x 10-5
Kip > Ksp
Then, CaSO4 will precipitate.

Calculation of ion concentrations:

CaCl2 dissociates into Ca2+ and 2Cl- ions.
Therefore, [Ca2+] = 0.01 M, [Cl-] = 0.02 M

Na2SO4 dissociates into 2Na+ and SO42- ions.
Therefore, [Na+] = 0.04 M, [SO42-] = 0.02 M

Calculation of ion product (Qsp):

Qsp = [Ca2+][SO42-]
= (0.01)(0.02)
= 2 x 10^-4

Comparison of Qsp with Ksp:

Ksp = 2.4 x 10^-5

Since Qsp > Ksp, the solution is supersaturated and precipitation will occur.

Explanation of the answer:

When CaCl2 and Na2SO4 are mixed, the concentrations of Ca2+ and SO42- ions increase in the solution. The ion product Qsp, which is the product of the ion concentrations, is greater than the solubility product constant Ksp of CaSO4. This means that the solution is supersaturated with respect to CaSO4 and precipitation will occur. Both CaSO4 and Na2SO4 will precipitate from the solution. Therefore, the correct answer is option C.
