CHCl3 is tested prior to its use as anaesthetic, by: (A)  AgNO3+HCl  (B)  HCl  (C)  AgNO3  (D) none of these

Tardigrade Admin · Accepted Answer

Chloroform is tested by AgNO 3 before its use as anaesthetic because chloroform is oxidised by atmospheric air to a poisonous gas phosgene (carbonyl chloride) on standing for sometime. In this reaction, it also form HCl which give white ppt. with AgNO 3. Hence, chloroform is used only when it does not form white ppt. with AgNO 3.
