Solution
A sample of chloroform, before using as an anaesthetic, is tested after boiling with alc. KOH, with silver nitrate.
Explanation:
Chloroform is tested after boiling with alcoholic KOH and then adding silver nitrate.
- Boiling with alc. KOH breaks chloroform into chloride ions (Cl−).
- Adding AgNO3 gives a white precipitate of AgCl, confirming the presence of chloroform.
