Calculation of solubility: If we know the solubility product of a meagerly soluble salt like AgCl we can calculate the solubility of the salt and vice versa. The solubility product of a sparingly soluble salt at a particular temperature can be calculated from a knowledge of the solubility of the salt in water at that particular temperature. Our library is the biggest of these that have literally hundreds of thousands of different products represented. If there is a survey it only takes 5 minutes, try any survey which works for you. K sp When the solution becomes saturated with ions, that is, unable to hold any more, the excess solid settles to the bottom of the container and an equilibrium is established between the undissolved solid and the dissolved ions. Hence to find whether a precipitation can take place or not, ionic product of salt is calculated and it is then compared with the solubility product of the salt at the same temperature. The "thermodynamic solubility product constant," K s, at the given T and P is constant regardless of the concentrations of ions or of the presence of other ionic or molecular species in solution.
