Which statement about drying agents is correct?

Drying agents are substances that are used to remove water from organic solvents or reaction mixtures. When a drying agent is added to a wet solution, it absorbs moisture from the liquid. As the drying agent effectively removes the water, it can change the appearance of the solid form of the drying agent itself.

When the powder no longer forms clumps, it indicates that the drying agent has been able to effectively reduce the moisture content, which allows the particles to disperse more freely rather than sticking together in clumps due to the presence of water. This is a key indication that the drying agent is functioning properly and has successfully absorbed the water present in the solution.

In contrast, other outcomes, such as the solution turning cloudy, boiling rapidly, or the drying agent dissolving, do not accurately reflect how a drying agent performs. A solution may turn cloudy due to the presence of impurities or insufficient mixing, and boiling rapidly is generally not a sign of effective drying, rather it indicates a change in temperature that might be due to a variety of reasons unrelated to the action of the drying agent. Moreover, drying agents typically do not dissolve in the solvent they are used to dry, as their purpose is to remain as solids while absorbing moisture.

Thus, the statement that
