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