Ammonia may be prepared by heating ammonium chloride with:
Correct answer: C. Aqueous sodium hydroxide
- A. Water
- B. NaCl
- C. Aqueous sodium hydroxide
- D. H2S04
Explanation
Ammonium chloride which is a salt in nature will react with base sodium hydroxide to form ammonia gas, water and sodium chloride. Ammonium chloride will dissociate in water, it will not react with NaCl or dilute H2SO4. If a mixture of pure (solid) ammonium chloride and concentrated sulfuric acid is heated, hydrogen chloride gas will evolve.

About Reactions of Group I Elements
Group I elements have one valence electron, so their reactivity increases down the group as ionisation energy decreases. Their reactions with water, oxygen, hydrogen and halogens produce hydroxides, oxides, hydrides and halides, while the behaviour of lithium differs from the heavier metals because of its small ionic size.
