According to Lowry - Bronsted Acid & Base Concept, H2O is:
Correct answer: C. An amphoteric species
- A. An acid
- B. A base
- C. An amphoteric species
- D. A salt
Explanation
Water is an example of an amphiprotic substance. This means it is able to donate a proton or accept a proton. The Bronsted/Lowry theory defines an acid or base by how they behave in a chemical reaction. Depending on what water reacts with it can act as an acid (proton donor) or a base (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.
