Which of the following concept is also known as proton-donor acceptor system
Correct answer: A. Bronsted-Lowry
- A. Bronsted-Lowry
- B. Lewis
- C. Lux-Flood
- D. Usanovich
Explanation
The correct answer is Bronsted-Lowry. This theory specifically defines acids and bases in terms of their ability to donate or accept protons (H+ ions). This directly relates to the concept of a proton-donor acceptor system. The Lewis theory focuses on the transfer of electron pairs rather than protons. The Lux-Flood concept deals with oxide ions, while the Usanovich theory is a more general system that includes various types of transfer, not limited to protons.

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.
