What is ksp chemistry definition

Calculation of K sp from Equilibrium Concentrations. We began the chapter with an informal discussion of how the mineral fluorite is formed. What is the solubility product of fluorite? First, write out the K sp expression, then substitute in concentrations and solve for K sp :. Hence, an equilibrium expression is written for the process. You must keep in mind that the solid silver chloride does not have a variable concentration and is therefore not included in the expression.

This is the solubility product principle. Solubility Product Formula. The solubility product constant is used to describe the saturated solutions of ionic compounds having relatively low solubility. A saturated solution is said to be in a state of dynamic equilibrium between the ionic compound and the undissolved solid.

The Ksp formula is given in the form of the following equation:. The general equilibrium constant is written as follows:. Significance of the Solubility Product. The solubility depends on a several numbers of parameters which includes the lattice enthalpy of salt and solvation enthalpy of ions in the solution that are of most importance.

Let us learn about the significance of the solubility product in detail. Whenever a salt is dissolved in a solvent, the strong forces of attraction of solute that are the lattice enthalpy of its ions need to be overcome by the interactions between the ions and the solvent.

Solubility product constant is simplified equilibrium constant Ksp defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates in water. The higher the solubility product constant, the more soluble the compound.
