A) muriatic air .
B) liquifiable air .
C) alkaline air .
D) acidic air.
Choose the correct ans
Answers
Answer:
" Option C - Alkaline air " is correct.
Ammonia was initially called as Alkaline air due to its basic nature.
Explanation:
Ammonia is an alkaline gas. It is a weak alkali and hence it is called alkaline air. It is pungent smelling. Ammonia gas can be liquefied easily. It is lighter than air. It is colourless. It is also highly soluble in water. Upon reacting with HCl it forms white solid. It is not a supporter of combustion. It is not poisonous. It has low boiling point. It has low freezing point.
Answer:
OPTION C
Explanation:
Ammonia is called alkaline air because of its basic nature . Normally an alkali is a substance which when dissolved in water yields hydroxyl ions as the only negatively charged ion .
The ammonia is also prepared by heating slaked lime with another substance called "sal ammoniac".
The gas is found in the atmosphere and it is also found in water since it is highly soluble in water .
Ammonia is always collected by the downward displacement of air because it is lighter than air and soluble in water . Therefore ammonia cannot be collected by downward displacement of water .
Ammonium salt heated with an alkali will give the corresponding salt , ammonia and water vapour is evolved .
