A $0.0020\, M$ aqueous solution of an ionic compound $Co \left( NH _{3}\right)_{5}\left( NO _{2}\right) Cl$ freezes at $-0.00732^{\circ} C$. Number of moles of ions which 1 mole of ionic compound produces on being dissolved in water will be : $\left( k _{ f }=1.86^{\circ} C / m \right)-$
- 1
- 2
- 3
- 4
The Correct Option is B
Solution and Explanation
$i =\frac{\Delta T _{ f }}{ k _{ f } \cdot m }$
$=\frac{0.00732}{1.86 \times 0.002}=\frac{0.00732}{0.00372}$
$i =2$
Compound will be $\left.\left[ Co \left( NH _{3}\right)_{5}\right] NO _{5} NO _{2}\right] Cl$
Total possible ions $=2$

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.
