Question

How can a mixture of chloroform, aniline, and benzoic acid be separated?

Answer 1

Answer:

These compounds can be separated by selective extraction using the fact that aniline, aminobenzene will be found in an aqueous using the weak HCl solution. Chloroform being quite dense means the after three extractions, both organic acids phenol and benzoic will remain in the bottom layer. The free base aniline is recovered by base addition NaOH. The two acids remaining in the chloroform are easy to separate as phenol is a weak acid that can be liberated with the bicarbonate. Benzoic is a strong acid thus can be selectively extracted from the chloroform.

Answer 2

Answer:

suitable method for separating a mixture of aniline and chloroform would be steam distillation. ... Here, since aniline is a non-polar aromatic compound , it doesn't dissolve in water whereas chloroform is soluble( though weak interactions present). Therefore, steam distillation is an ideal method for their separation
