Question

Ammonia gas can be dried by (A) cone H2SO4 (B) P2O5 (C) CaCl2 (D) quicklime

Tardigrade Admin · Accepted Answer

Quicklime (CaO) is used for drying NH3 gas because both are basic, do not react. On the other hand, H2SO4 and P2O5 are acidic, reacts with ammonia forming salts. CaCl2 forms complex with ammonia.

quicklime

Quicklime $(C a O)$ is used for drying $N H_{3}$ gas because both are basic, do not react. On the other hand, $H_{2} S O_{4}$ and $P_{2} O_{5}$ are acidic, reacts with ammonia forming salts. $C a C l_{2}$ forms complex with ammonia.
