The Correct Option is C
Solution and Explanation
$H_3PO_3$ is a dibasic acid.
$ {H_3PO_3 + 2 KOH -> K_2HPO_3 + 2H_2O}$
$\frac{M_AV_A}{n_A} = \frac{M_BV_B}{n_B}$
$\frac{0.1 \times 20}{1} = \frac{0.1 \times V_B}{2}$
$V_B$ = 40 mL.

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.
