1.	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 ?
Answer» SOLUTION :The mixture is shaken with a dilute solution of `NaHCO_(3)` and EXTRACTED with ether or chloroform when nitrobenzene GOES into the organic layer. DISTILLATION of the solvent gives nitrobenzene. The filtrate is acidified with dil. HCl when benzoic acid gets precipitated. The solution is cooled and benzoic acid is obtained by filtration.
