Description
Understanding the solubility product (Ksp) is vital for determining a substance's dissolution extent in a solution. Ksp represents the dynamic equilibrium between dissolving ions and the solid lattice. The Ksp expression is the product of ion concentrations, useful for compounds with very low solubility.
