A misture of camphor and benzoic acid can be separated by :

A

Sublimation

B

Chemical method

C

Fractional Crystallisation

D

Extractin with solvent

Text Solution

Verified by Experts

The correct Answer is:
B
The mixture is reacted with aqueous `NaOH` solution when benzoic acid becomes water soluble as sodium salt and can be separated. It can be regenerated by reacting the solution with dilute `HCl`.
`underset("(Soluble)")(C_(6)H_(5)COOH+NaOH rarr C_(6)H_(5)COONa+H_(2)O)`
`C_(6)H_(5)COONa+HCl rarr underset("(Regenerated)")(C_(6)H_(5)COOH)+HCl`
