What is Solubility Product?
The equilibrium constant (Ksp) for the dissolution of a slightly soluble ionic compound. Ksp = [cation]^m[anion]^n for MₘAₙ. A smaller Ksp indicates lower solubility. Used to predict precipitation and calculate ion concentrations in saturated solutions.

The equilibrium constant (Ksp) for the dissolution of a slightly soluble ionic compound. Ksp = [cation]^m[anion]^n for MₘAₙ. A smaller Ksp indicates lower solubility. Used to predict precipitation and calculate ion concentrations in saturated solutions.
Ksp values are used to predict whether a precipitate will form when two solutions are mixed (Q vs Ksp comparison). They are used in water treatment to remove heavy metal ions by precipitation. Ksp calculations guide fractional precipitation in analytical chemistry.
Many sparingly soluble compounds involve toxic heavy metals (lead, mercury, barium). Understanding Ksp helps assess the risk of ion release into water supplies and environments.
The formula or notation for Solubility Product is: Ksp = [Aᵐ⁺]ᵐ[Bⁿ⁻]ⁿ for AₙBₘ(s) ⇌ mAⁿ⁺ + nBᵐ⁻
