For drying ammonia gas sulphuric acid is used as dehydrating agent

Answer: Option B : B Sulphuric acid reacts with ammonia to form ammonium sulphate H 2 S O 4 + 2 N H 3 → ( N H 4 ) 2 S O 4 Therefore, CaO is used to dry ammonia gas C a O + H 2 O → C a ( O H ) 2

Question -

For drying ammonia gas sulphuric acid is used as dehydrating agent – True or False?

Options:

A . True

B . False

C . Both

N H_{3}

and

H_{2} N - N H_{2}

are equally basic.

D . Neither of them are basic

Answer: Option B
:
B
Sulphuric acid reacts with ammonia to form ammonium sulphate

H_{2} S O_{4} + 2 N H_{3} \to (N H_{4})_{2} S O_{4}

Therefore, CaO is used to dry ammonia gas

C a O + H_{2} O \to C a (O H)_{2}
