Question

Quizplus · Accepted Answer

The solubility product constant (Ksp) for a compound is given by the product of the molar concentrations of its ions, each raised to the power of its coefficient in the balanced dissolution equation. For KAl(SO4)2·12H2O, the dissolution in water would produce K+, Al3+, and 2 SO4^2- ions. The correct expression for Ksp does not include the solid compound in the denominator and correctly accounts for the stoichiometry of the ions produced. Option D correctly represents this with [K+] × [Al3+] × [SO4^2-]^2, reflecting the dissolution of one formula unit of the compound into its constituent ions.
