Van't Hoff factors of equimolal solutions of sodium chloride, barium chloride and glucose in water are
- $2, 3, 0$ respectively
- $2, 3, 6$ respectively
- $2, 3, 4$ respectively
- $2, 3, 1$ respectively
The Correct Option is D
Solution and Explanation
van't Hoff factor, $i = 2$
$ { BaCl_{2(aq)} -> Ba^{2+}_{(aq)} + 2 Cl^{-}_{(aq)}} ,i = 3$
Glucose does not undergo dissociation or association hence, $i = 1$.

Solutions
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 solvent is 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.
