A mixture contains nitre, common salt and silver chloride as the components. The different separation techniques involved are_____, _______ and _______.

Explanation

To separate a mixture containing nitre (potassium nitrate), common salt (sodium chloride), and silver chloride, we can use the following separation techniques:

### Step-by-Step Solution:

1. **Solvent Extraction**:
- **Explanation**: This technique is used to separate components based on their solubility in different solvents. In this case, we can use water as a solvent.
- **Process**: When water is added to the mixture, the common salt (sodium chloride) dissolves in water, while silver chloride (which is insoluble in water) remains as a solid. Nitre (potassium nitrate) is also soluble in water.
