What solely affects the solubility product constant, Ksp?

The solubility product constant, ( K_{sp} ), is a specific equilibrium constant that applies to the dissolution of sparingly soluble ionic compounds in a saturated solution. It reflects the condition at which the solid phase is in equilibrium with its ions in solution. The solubility product constant is defined under specific conditions, typically at a constant temperature.

For ( K_{sp} ), temperature is the only factor that solely affects its value. As temperature changes, the equilibrium between the solid and dissolved species can shift, which may lead to an increase or decrease in solubility. This change in solubility alters the concentration of the ions in solution and consequently affects ( K_{sp} ).

Pressure can influence the solubility of gases, but it generally has minimal to no effect on the solubility of solid ionic compounds in liquid solutions since solids and liquids are generally incompressible. Additionally, while the concentration of solutes affects the current state of the equilibrium, it does not change the ( K_{sp} ) value for a given temperature. Moreover, the presence of other compounds can affect the solubility of a salt through common ion effects or complexation; however, these do not alter the intrinsic (
