How can a mixture of camphor and benzoic acid be separated without using column chromatography?

Explanation

To separate a mixture of camphor and benzoic acid without using column chromatography, we can follow these steps:

### Step-by-Step Solution:

1. **Dissolve the Mixture**: Begin by dissolving the mixture of camphor and benzoic acid in water. Since camphor is not very soluble in water, it will remain as a solid while the benzoic acid will dissolve.

2. **Add Sodium Bicarbonate Solution**: Next, add a sodium bicarbonate (NaHCO₃) solution to the mixture. The benzoic acid will react with sodium bicarbonate to form sodium benzoate, which is soluble in water, while camphor will remain undissolved.
