Ammonia can be dried by :

A

`conc. H_(2)SO_(4)`

B

`P_(4)O_(10)`

C

`CaCO`

D

`anhydrous CaCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
It reacts with conc. `H_(2)SO_(4),P_(4)O_(10)` and anhydrous `CaCl_(2)` but not with `CaO`.
`2NH_(3)+H_(2)SO_(4) to (NH_(4))_(2)SO_(4)" , "P_(4)O_(10)+ 12NH_(3) to 4(NH_(4))_(3)PO_(4)+6H_(2)O`.
`CaCl+8NH_(3) to CaCl_(2).8NH_(3)." , "CaO+H_(2)O to Ca(OH)_(2)`.
