Final answer:
True, if Q is less than Ksp, the solution is unsaturated, and no precipitation occurs until the system reaches equilibrium.
Step-by-step explanation:
If the reaction quotient Q is compared to the solubility product constant (Ksp), it predicts whether a solid will precipitate from a solution. The statement "If Q < Ksp, the solution is unsaturated and no precipitation will occur" is True. When Q is less than Ksp, the solution can still dissolve more solute until it reaches equilibrium where Q equals Ksp. At this point, the solution is saturated but no precipitation occurs because the rate of dissolution is equal to the rate of precipitation.
In contrast, if Q is greater than Ksp, the solution is supersaturated and precipitation of the solid will occur to return the system to equilibrium. When Q equals Ksp, the system is at equilibrium and no net change in the amount of dissolved solid occurs.
