A mixture contains benzoic acid and nitrobenzene. How can this mixture be separated into its constituents by the technique of extraction using an appropriate chemical reagent ?

Explanation

To separate a mixture of benzoic acid and nitrobenzene using the technique of extraction, follow these steps:

### Step-by-Step Solution:

1. **Dissolve the Mixture in Water**: Begin by dissolving the mixture of benzoic acid and nitrobenzene in water. Since benzoic acid is soluble in water, it will dissolve, while nitrobenzene, being a non-polar compound, will not.

**Hint**: Remember that benzoic acid is a weak acid and will ionize in water, increasing its solubility.
