Which of the following statements is correct?
Correct answer: A. H3PO3 is dibasic and reducing
- A. H3PO3 is dibasic and reducing
- B. H3PO3 is tribasic and reducing
- C. H3PO3 is tribasic and non-reducing
- D. H3PO3 is dibasic and non-reducing
Explanation
In the structure of H3PO3, two -OH groups are present, so it is dibasic acid. In it one P-H bond is present, so it provides hydrogen and due to such hydrogen it acts as a reducing agent.

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.
