Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$\underset{0.1 \,M }{ AgNO _{3}} \longrightarrow Ag ^{+}+\underset{0.1 m \rightarrow \text { volume }= N _{3}^{-}}{ N _{1}}$
$M_{1}\, V_{1}=M_{2}\, V_{2} $ Equal volume
$0.1 \times V=M_{2}\left[V_{1}+V_{2}\right] \,\,\,\left[N_{1}=V_{2}=V\right]$
$0.1 \times V=M_{2}[V+V]$
$M _{2}=\frac{0.1 V }{2 V }=0.05$
$M_{1}\, V_{1}=M_{2}\, V_{2} $ Equal volume
$0.1 \times V=M_{2}\left[V_{1}+V_{2}\right] \,\,\,\left[N_{1}=V_{2}=V\right]$
$0.1 \times V=M_{2}[V+V]$
$M _{2}=\frac{0.1 V }{2 V }=0.05$

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.
