A

CaO

B

`HNO_(3)`

C

`P_(2)O_(5)`

D

`CuSO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`:. NH_3 ` reacts with `P_(2)O_(5) or CaCl_(2) or "Conc" H_2SO_4`. Therefore , it cannot be dreid over either of them . `CuSO_(4) and HNO_(3) ` are not drying agent . `NH_3` can be dried over CaO only because it is a drying agent with which it does not react .
