Correct option is C
The correct answer is (C) HCl – NH₄OH.
Here’s the reasoning:
Here’s the reasoning:
- Ammonium chloride (NH₄Cl) is formed when ammonium ions (NH₄⁺) react with chloride ions (Cl⁻).
- HCl (hydrochloric acid) is a strong acid that will dissociate to give H⁺ and Cl⁻ ions.
- NH₄OH (ammonium hydroxide) is a weak base that dissociates to give NH₄⁺ and OH⁻ ions.
- When HCl reacts with NH₄OH, the NH₄⁺ ions from ammonium hydroxide combine with the Cl⁻ ions from hydrochloric acid to form NH₄Cl (ammonium chloride).
- The reaction is:
Therefore, the acid-base pair HCl – NH₄OH produces ammonium chloride (NH₄Cl)
Additional Knowledge:
Additional Knowledge:
- (a) HNO₃ - NH₄OH: This will produce ammonium nitrate (NH₄NO₃), not ammonium chloride.
- (b) H₂SO₄ - NH₄OH: This will produce ammonium sulfate ((NH₄)₂SO₄), not ammonium chloride.
- (d) HCl – NaOH: This will produce sodium chloride (NaCl), not ammonium chloride.
