The equilibrium solubility of Ca (So3)2 is
Ca (So3)2 ⇋⇋ Ca2 + 2(SO3)
The Ksp (Solubility product) expression looks like this:
Ksp = [Ca2+] [SO3-]2
Ca (So3)2 generates 1 mol of Ca2+ whereas 2 mol of SO3– per mol.
[Ca2+] = 1.18*10^-4 M
[I–] = (2) × 1.18*10^-4 M
So, [I–] = 2.36 × 10^-4M
On Replacing these values in the Ksp equation.
Ksp = (1.18*10^-4M) (2.36 × 10^-4M)2
So, Ksp = 2.7848 x 10^-8 M2
What is a Solubility Product?
- The solubility product constant, abbreviated Ksp, is a condensed equilibrium constant that describes the equilibrium between a solid and its associated ions in a particular solution.
- Its value reveals how much a substance can dissociate in water. The substance is more soluble the higher the solubility product constant. The sum of the ion concentrations for a particular salt results in the Ksp expression.
- The saturated solutions of relatively low solubility ionic substances are described using the solubility product constants.
- The dissolved and dissociated ionic component and the undissolved solid are in a dynamic equilibrium state in a saturated solution.
