C)the concentration of the solution will remain the same.
D)the volume of solution will increase.
E)a supersaturated solution will be produced.

Quizplus · Accepted Answer

When more solid sucrose is added, it will dissolve and maintain equilibrium with the existing solution. Therefore, the concentration of the solution will remain the same. Adding more solid sucrose will not change the original equilibrium concentration. The volume of the solution will only increase if the added sucrose is not fully dissolved, but that is not specified in the question. A supersaturated solution would only be produced if the amount of solid sucrose added was beyond the solubility limit of the solution.
