A miscible mixture of benzene and chloroform can be separated by :

Options

A. sublimation
B. distillation
C. filtration
D. Crystallisation

Explanation

To separate a miscible mixture of benzene and chloroform, we can use the method of distillation. Here’s a step-by-step solution:

### Step 1: Understand the Components
- **Benzene (C6H6)** has a boiling point of approximately **80°C**.
- **Chloroform (CHCl3)** has a boiling point of approximately **61.5°C**.

### Step 2: Identify the Separation Method
Since both substances are liquids and have different boiling points, we can utilize **distillation** as the separation method. Distillation is effective when separating components of a mixture that have significantly different boiling points.

### Step 3: Set Up the Distillation Apparatus
- Prepare a distillation setup which includes a distillation flask, a heat source, a condenser, and a receiving flask.
- Place the miscible mixture of benzene and chloroform in the distillation flask.

### Step 4: Heat the Mixture
- Gradually heat the mixture. As the temperature reaches around **61.5°C**, chloroform will start to vaporize since it has a lower boiling point than benzene.

### Step 5: Collect the Vapors
- The vaporized chloroform will travel through the condenser where it will cool down and condense back into a liquid.
- Collect the condensed chloroform in the receiving flask.

### Step 6: Continue Heating
- Continue heating until the temperature reaches around **80°C**. At this point, the benzene will start to vaporize.
- You can stop the distillation once most of the chloroform has been collected and only benzene remains in the distillation flask.

### Step 7: Result
- You will have separated chloroform in one flask and benzene in another flask.

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