Solution

The correct option is C An equilibrium has been established
The correct statement regarding a saturated solution of salt in water is that an equilibrium has been established.
The rate of dissolution of solute into the solution is equal to the rate of coming out of the solution.
Two rates are equal which represents equilibrium condition at which optimum amount of solute is present in the solution.
Note: A solution which contains the maximum amount of the solute that can be dissolved in a given amount of the solvent at a particular temperature is called a saturated solution.
