Answer

Answer:

C. Each second, the amount of solid sodium chloride that dissolves equals the amount of solid sodium chloride that recrystallizes.

Explanation:

Step1: Analyze option A

In a saturated solution at dynamic equilibrium, the concentration of dissolved particles remains constant. But this is a result of the dynamic equilibrium process (dissolving and recrystallizing at equal rates), not the best description of how dynamic equilibrium relates.

Step2: Analyze option B

In a saturated solution, solid does dissolve and recrystallize simultaneously. So, the statement “No more solid dissolves in a saturated solution” is incorrect.

Step3: Analyze option C

Dynamic equilibrium in a saturated solution of sodium chloride means that the rate of dissolution of solid sodium chloride is equal to the rate of recrystallization of sodium chloride. So, each second, the amount of solid sodium chloride that dissolves equals the amount of solid sodium chloride that recrystallizes. This is the best description of dynamic equilibrium.

Step4: Analyze option D

The statement “Each second, solid sodium chloride dissolves and solid sodium chloride recrystallizes” does not mention the equality of rates. So, it is not the best description of dynamic equilibrium.
