Question

Ammonia may be prepared by heating ammonium chloride with:

Options
  • 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.

This reactant is not used in this reaction.
