Question

Hydrochloric acid (strong acid) reacts with Ammonia (a weak base) to give ___________ and water.

  1. Ammonium chloride
  2. Ammonium hydroxide
  3. Ammonia
  4. Both a and b

hintHint:

Ammonia is a weak base that reacts with HCl forming a compound called ammonium chloride. 
NH3 + HCl = NH4Cl

The correct answer is: Ammonium chloride


    Hydrochloric acid (strong acid) reacts with Ammonia (a weak base) to give Ammonium chloride and water.
    • The conjugate acid of ammonia (ammonium), which is a weak base, must be a comparably stronger acid.
    • That indicates that the final solution is slightly acidic after mixing equal parts of everything.
    • Thus, ammonium chloride will be produced white fumes, combining HCl gas with gas NH3 (NH4Cl).
