An acid-base reaction is the transfer of proton from an acid to a base. This is according to
Correct answer: B. Bronsted-Lowry concept
- A. Arrhenius concept
- B. Bronsted-Lowry concept
- C. Lewis concept
- D. All of the above
Explanation
The correct answer is the Bronsted-Lowry concept, which specifically characterizes acids as proton donors and bases as proton acceptors, highlighting the transfer of a proton. The Arrhenius concept is focused on the formation of ions in aqueous solutions without explicit mention of proton transfer. The Lewis concept involves electron pair transfers, making it unrelated to proton transfer in acid-base reactions. Thus, only the Bronsted-Lowry concept correctly defines an acid-base reaction as a proton transfer.

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.
