Question

Which of the following statements is true? (a) HClO₄ is a weaker acid than HClO₃(b) HNO₃ is a stronger acid than HNO₂(c) H₃PO₃ is a stronger acid than H₂SO₃(d) In aqueous medium HF is a stronger acid than HCl

Answer 1

HNO₃ is stronger acid than HNO₂ as in HNO₃, N is present in +5 oxidation state so it is more electron deficient then N in HNO₂ (which is in +3 oxidation state). So the nitrogen in +5 oxidation is more electron deficient than in +3.

So it acts as a better Lewis Acid being more electron deficient.
