A

Fehling solution

B

Ammonical `Cu_2Cl_2` soln.

C

`AgNO_3` soln.

D

`BaCl_2` soln.

Text Solution

Verified by Experts

The correct Answer is:
C
On exposure to sunlight and air , `CHCl_3` is slowly oxidized to highly poisonous carbonyl chloride, `COCl_2` and HCl rendering it unfit for use as anaesthetic. The presence of HCl is tested with `AgNO_3` solution.
