Ammonia can be dried by `:`

A

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

B

`P_(4)O_(10)`

C

`CaO`

D

anhydrous `CaCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
3
It reacts with conc. `H_(2)SO_(4),P_(4)O_(10)` and anhydroous `CaCl_(2)` but not with `CaO`.
`2NH_(3)+H_(2)SO_(4)rarr(NH_(4))_(2)SO_(4)`
`P_(4)O_(10)+12NH_(3)rarr4(NH_(4))_(3)PO_(4)+6H_(2)O`
`CaCl_(2)+8NH_(3)rarrCaCl_(2).8NH_(3)`
`CaO+H_(2)O rarrCa(OH)_(2)`
