Law Of Chemical Equilibrium And Equilibrium Constant

The correct option is (A): A> C> B

In chemistry, the formation of a precipitate is related to the concept of solubility product (K_sp). The solubility product is a constant for a given substance at a specific temperature, representing the maximum product of ion concentrations in a saturated solution. The ionic product is the product of the concentrations of ions in a solution raised to the power of their stoichiometric coefficients in the balanced equation of dissolution.

A precipitate forms when the ionic product exceeds the solubility product (K_sp), as this indicates that the solution is supersaturated with respect to the dissolved ions. Supersaturation leads to excess ions pairing to form an insoluble solid, i.e., a precipitate, because the solution can no longer maintain such high ion concentrations in the dissolved state.

Therefore, a precipitate is formed if the ionic product is greater than the solubility product.
