At same temperature, which pair of the following solutions are isotonic solutions ?
Updated On: Apr 30, 2024
- 0.2 M $BaCl_2$ and 0.2 urea
- 0.1 M urea and 0.1 M NaCl
- 0.1 M NaCl and 0.1 M $K_2S0_4$
- 0.1 M $Ba(N0_3)_2 $ and $ 0.1 M Na_2SO_4$

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Two solutions are isotonic if they have same molar concentrations of particles in solution.
0.1 M $Ba(NO_3)_2$ = 0.3 M ion concentration
0.1 M $Na_2SO_4$ = 0.3 M ion concentration
0.1 M $Ba(NO_3)_2$ = 0.3 M ion concentration
0.1 M $Na_2SO_4$ = 0.3 M ion concentration

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.
