A miscible mixture of `C_(6)H_(6)+CHCl_(3)` can be separated by

Options

A. Sublimation
B. Distillation
C. Filtration
D. Crystallisation

Answer

To solve the problem of separating a miscible mixture of benzene (C₆H₆) and chloroform (CHCl₃), we can follow these steps:

### Step 1: Understand the Properties of the Mixture
- Benzene (C₆H₆) and chloroform (CHCl₃) are both liquids and are miscible, meaning they can mix in all proportions without separating into different phases.

**Hint:** Identify the physical state and miscibility of the components in the mixture.

### Step 2: Evaluate Separation Methods
- **Sublimation:** This method is not applicable here because both substances are liquids. Sublimation is used for solids that turn directly into gas without passing through the liquid state.

**Hint:** Recall the definition of sublimation and its applicability to states of matter.

- **Filtration:** This method is used to separate solids from liquids. Since both benzene and chloroform are liquids, filtration is not a suitable method.

**Hint:** Consider what filtration separates and the states of the substances involved.

- **Crystallization:** This method is used to separate solids from liquids by forming crystals. Since both components are liquids, crystallization cannot be applied.

**Hint:** Think about the process of crystallization and its requirements for solid formation.

### Step 3: Identify the Suitable Method
- **Distillation:** This method is based on the difference in boiling points of the components. Benzene has a boiling point of 80°C, while chloroform has a boiling point of 61.2°C. Since they have different boiling points, distillation can effectively separate them.

**Hint:** Recall the principle of distillation and how boiling points are used to separate components.

### Step 4: Describe the Distillation Process
- In the distillation process, the mixture is heated. As the temperature rises:
- Chloroform will vaporize first at around 61.2°C.
- The vapors of chloroform can be collected and condensed back into liquid form.
- After all the chloroform has been distilled off, the temperature can be increased to 80°C to distill benzene.

**Hint:** Visualize the distillation apparatus and the sequence of vaporization and condensation.

### Conclusion
The miscible mixture of benzene and chloroform can be separated by **distillation** due to their different boiling points.

**Final Answer:** Distillation
