Question

If $Q_{sp}>K_{sp}$, then precipitation will not occur. If true write 1, else write 0.

Answer 1

When the ionic product exceeds the solubility product, the equilibrium shifts towards left-hand side, i.e., increasing the concentration of undissociated molecules of the electrolyte. As the solvent can hold a fixed amount of electrolyte at a definite temperature, the excess of the electrolyte is thrown out from the solutions as precipitate.
