(N/A) limited amount of salt or sugar dissolves in a given amount of water at room temperature. If a thick sugar syrup is prepared at a higher temperature and then cooled to room temperature,sugar crystals separate out. $A$ solution that contains sugar crystals in equilibrium with dissolved sugar is called a saturated solution. $A$ saturated solution is one in which no more solute can be dissolved at a given temperature.
In a saturated solution,a dynamic equilibrium exists between the solute molecules in the solid state and the solute molecules in the solution.
Example: $Sugar_{(solid)} \rightleftharpoons Sugar_{(solution)}$
At equilibrium: $\text{Rate of dissolution of sugar} = \text{Rate of crystallisation of sugar}$.
In the forward reaction,the dissolution of the solid into the solution occurs,and in the reverse reaction,the crystallisation of the solute occurs.
Dynamic nature: The dynamic nature of this equilibrium can be confirmed using radioactive sugar. If radioactive sugar is added to a saturated solution of non-radioactive sugar,after some time,radioactivity is observed in both the solution and the solid sugar. This indicates that there is a continuous exchange of molecules between the two phases,even though the net concentration remains constant.
