Question

At the state of dynamic equilibrium, for solute $+$ solvent $\leftrightharpoons$ solution.

• A. Rate of dissolution = Rate of unsaturation.
• B. Rate of dissolution $=$ Rate of unsaturation.
• C. Rate of dissolution = Rate of saturation
• D. Rate of crystallization = Rate of saturation.

Answer 1

Answer: (B)

Number of solute particles going into solution will be equal to the solute particles separating out and a state of dynamic equilibrium is reached.
solute $+$ solvent $\leftrightharpoons$ solution.
i.e., rate of dissolution $=$ rate of unsaturation.
