Solubility Product Principle
What is Solubility Product Principle?
The solubility product principle states that in a saturated solution of a sparingly soluble electrolyte, the ionic concentration product (ion product, Q) equals the solubility product constant (Ksp) at equilibrium. If Q < Ksp, the solution is unsaturated and more solid can dissolve; if Q > Ksp, precipitation will occur until Q equals Ksp; if Q = Ksp, the solution is at equilibrium (saturated). This principle governs precipitation reactions, qualitative analysis schemes, and the formulation of sparingly soluble drug compounds.
