Vedclass · Answer

(C) The correct answer is $(C)$.Chloroform $(CHCl_3)$ is tested for purity before use as an anaesthetic by adding aqueous silver nitrate $(AgNO_3)$ solution.Pure chloroform does not react with aqueous $AgNO_3$ and thus does not form a white precipitate of silver chloride $(AgCl)$.If the chloroform has been oxidized to phosgene $(COCl_2)$ or contains impurities like $HCl$,it will react with $AgNO_3$ to form a white precipitate of $AgCl$.
