Two open beakers one containing a solvent and the other containing a mixture of that solvent with a non volatile solute are together sealed in a container. Over time:
the volume of the solution and the solvent does not change
the volume of the solution increases and the volume of the solvent decreases
the volume of the solution decreases and the volume of the solvent increases
the volume of the solution does not change and the volume of the solvent decreases

The Correct Option isB
Solution and Explanation
As solvent is pure and volatile, so it will vapourise and increase vapour pressure till that vapour pressure will come in equilibrium so volume decrease. As in solution, there is non-volatile solute, so it will not vapourise for vapour pressure to be in equilibrium solvent vapour will come towards the solution. So, the volume of solution increase. So, the volume of the solution increases and the volume of the solvent decreases.
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
Solid Solutions - In these solutions, the solventis in a Solid-state.
Liquid Solutions- In these solutions, the solvent is in a Liquid state.
Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
