For each compound, write an equation showing how the compound dissolves in water and write an expression for Ksp.
When a solution becomes saturated and a precipitate forms, a cloudiness appears, which is the insoluble solute. Small amounts of ionized solute remain in solution. A representation of the equilibrium relative to the concentrations of the ions is referred to as the: “Solubility Product” or the “Solubility-Product Constant” : Ksp
CaSO4·2H2O CaSO4 + 2H2O.
Calcium Sulfate = Anhydrite (mineral) + Dihydrogen Monoxide
Reaction Type: Decomposition
AgCl(s) ⇌ Ag+(aq) + Cl¯(aq)
Ksp = [Ag+] [Cl¯]
