Question:

We are given with three NaCl samples and their Van't Hoff factors. Which is correct option ?
SampleVan't Haff Factor 
Sample - 1 (0.1 M)\(i_1\)
Sample - 2 (0.01 M)\(i_2\)
Sample - 3 (0.001 M)\(i_2\)

  • \(i_1=i_2=i_3\)

  • \(i_1>i_2>i_3\)

  • \(i_1>i_2>i_3\)

  • \(i_1>i_3>i_2\)

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:

  1. Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
  2. 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.
  3. Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
