A proton acceptor is a:
Correct answer: A. Bronsted-Lowry base
- A. Bronsted-Lowry base
- B. Bronsted-Lowry acid
- C. Lewis acid
- D. Lewis base
Explanation
According to the Brønsted-Lowry theory, a base is defined as a substance that can accept a proton (H⁺). Ammonia (NH₃) is a classic example of a proton acceptor.

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.
