Which of the following oxyacid(s) on heating undergo disproportionation, giving a product containing the underlined element in a LOWER oxidation state?
Options:(select one or more)
Answer:
A, B, D
Solution:
4H₃PO₃ → 3H₃PO₄ + PH₃ (P: +3 → +5 and −3); 3HNO₂ → HNO₃ + 2NO + H₂O (N: +3 → +5 and +2); 2HClO₂ → HClO₃ + HClO (Cl: +3 → +5 and +1). H₃PO₄ (P already +5) does not disproportionate on heating.
