The conjugated acid of NH₃ is :
Correct answer: A. NH₄⁺
- A. NH₄⁺
- B. NH
- C. NH₂
- D. NH₂⁻
Explanation
A conjugate acid is formed when a base accepts a proton (H⁺). Ammonia (NH₃) acts as a base and accepts a proton to form NH₄⁺. Hence, the conjugate acid of NH₃ is ammonium ion.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
