A mixture contains three components namely camphor powder, common salt and water. These can be separated by

Options

A. filtration and distillation.
B. filtration, sedimentation and decantation.
C. sublimation and distillation.
D. sublimation, sedimentation and decantation.

Explanation

To separate a mixture containing camphor powder, common salt, and water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**: The mixture consists of camphor powder (which is insoluble in water), common salt (which is soluble in water), and water.

2. **Filtration**:
- First, we will perform filtration. Since camphor is insoluble in water, we can use a filter paper to separate it from the mixture.
- Pour the mixture through a filter paper placed in a funnel. The camphor powder will remain on the filter paper, while the saltwater solution will pass through.

3. **Collect the Filtrate**:
- The liquid that passes through the filter paper is the saltwater solution (common salt dissolved in water). The camphor will be left behind on the filter paper.

4. **Distillation**:
- Now, we have a solution of common salt in water. To separate the common salt from the water, we will use distillation.
- Heat the saltwater solution in a distillation apparatus. As the solution heats up, the water will evaporate because it has a lower boiling point compared to common salt.

5. **Condensation**:
- The water vapor will rise and pass through a condenser where it will cool down and condense back into liquid water, which can be collected separately.

6. **Salt Residue**:
- After all the water has evaporated, the common salt will remain as a solid residue in the distillation flask.

### Conclusion:
The two processes used to separate the components of the mixture are **filtration** (to separate camphor) and **distillation** (to separate common salt from water).
