Why are \(H_2SO_4\) and \(CaCl_2\), not suitable for drying ammonia gas? They
A.
are poisonous.
B.
pollute the gas
C.
are corrosive
D.
react with the gas
Correct answer is D
\(H_2SO_4\) and \(CaCl_2\) are not suitable for drying ammonia gas because they react with the gas.
Ammonia is a basic gas, and both \(H_2SO_4\) and \(CaCl_2\) are acidic. When these two substances react, they form salts that contain ammonia. This can contaminate the ammonia gas and make it unusable.
In addition, \(H_2SO_4\) is a corrosive substance, and \(CaCl_2\) can be harmful to breathe in. Therefore, it is not safe to use these substances to dry ammonia gas.
