How is solubility product is used to decide the precipitation of ions?

Answer»

Solution :(i) When the PRODUCT of molar concentration of the constituerx ions i.e., IONIC product exceeds the solubility PRODUCE then the compounds gets precipitated.
(II) When the ionic produce `gt K_(sp)` precipitation will occur and the solution is super saturated.
ionic product `lt K_(sp)` no precipitation and the solution is unsaturated.
ionic product `= K_(sp)` equilibrium exists and the solution is saturated.
In this way the solubility product finds USEFUL to decide whether an ionic compound gets precipitated when solution that contain the constituent ions are mixed.
