Question
Hydrochloric acid (strong acid) reacts with Ammonia (a weak base) to give ___________ and water.
- Ammonium chloride
- Ammonium hydroxide
- Ammonia
- Both a and b
Hint:
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).
