a. Calculate the solubility product of the following solutions:

i. A saturated aqueous solution of cadmium sulfide, CdS (solubility = 1.46 × 10^–11 mol dm^–3)

ii. A saturated aqueous solution of calcium fluoride, CaF₂, containing 0.0168 g dm^–3 CaF₂

b. Calculate the solubility in mol dm^–3 of zinc sulfide, ZnS. (Ksp =1.6 × 10^–23 mol² dm^–6)

c. Calculate the solubility of silver carbonate, Ag₂CO₃. (Ksp = 6.3 × 10^–12 mol³ dm^–9) Hint: you have to divide by 4 then take the cube root – can you see why? You should have a cube root button on your calculator
