Ksp (Solubility Product Constant)

The solubility product constant (Ksp) measures how much of an ionic compound dissolves in water to form a saturated solution. It’s the equilibrium point where the solid and its dissolved ions coexist without more dissolving. Ksp is calculated by multiplying the concentrations of the dissolved ions, each raised to the power of their respective numbers in the formula. A higher Ksp indicates the compound is more soluble, meaning more of it can dissolve in water, while a lower Ksp shows it’s less soluble. This helps predict whether a salt will dissolve or precipitate under given conditions.
