Answer:
When a sparingly soluble salt is placed in water, a very small amount of the salt dissolves in the water and a solution is formed. The solubility product, Ksp, determines the equilibrium that exists between the sparingly soluble salt and the ions that are dissolved in water.Sparingly soluble materials are those, which have lowered solubility. Usually materials are treated as sparingly soluble if 1g of material requires 30 to 100ml of solute to dissolve. In other words, a material will be sparingly soluble if the amount which can be dissolved in 100ml of solute ranges between 1g and 3,3g.
