The Correct Option is B
Solution and Explanation
Normality of a mixture
$(N)=\frac{N_{1} V_{1}+N_{2} V_{2}}{V_{1}+V_{2}}$
Normality $\left(N_{1}\right)$ of $H _{2} SO _{4}=$ molarity $\times$ basicity
$=0.2 \times 2=0.4\, N$
$N_{2}=0.2 \times 1=0.2\, N$
$V_{1}=100\, mL,\, V_{2}=200\, mL$
$N=\frac{0.4 \times 100+0.2 \times 200}{100+200}$
$=\frac{40 +40}{300}=\frac{80}{300}=0.2670\, N$
Normality of a mixture of acid and base $\left(N'\right)$
$N'=\frac{N_{1} V_{1} \sim N_{2} V_{2}}{V_{1}+V_{2}}$

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:
- 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.
