If ionic product is less than solubility product, what is the correct state of the solution?
Answer and explanation
Correct answer: Unsaturated
When Q, the ionic product, is less than Ksp, the current ion concentrations are below the equilibrium precipitation limit. The solution can still dissolve some of the salt without forming a precipitate, so it is unsaturated with respect to that salt. Saturation corresponds to Q = Ksp, while precipitation is favoured when Q > Ksp. The other options therefore do not fit the stated inequality.
