Arrange the acids (i) H2SO3(ii) H3PO3 and (iii) HClO3 in the decreas

1.	Arrange the acids (i) H2SO3(ii) H3PO3 and (iii) HClO3 in the decreasing order of acidity. (a) (i) > (iii) > (ii) (b) (i) > (ii) > (iii) (c) (ii) > (iii) > (I) (d) (iii) > (i)> (ii)
Answer» (d) (iii) > (i)> (ii) Acidity is directly proportional to oxidation number. As the oxidation number of S, P and Cl in H₂SO₃ , H₃PO₃ and HCIO₃ is +4, +3, +5 respectively. So decreasing order of acidity will be (iii) > (I) > (ii)

Arrange the acids (i) H2SO3(ii) H3PO3 and (iii) HClO3 in the decreasing order of acidity. (a) (i) > (iii) > (ii) (b) (i) > (ii) > (iii) (c) (ii) > (iii) > (I) (d) (iii) > (i)> (ii)

Answer»

(d) (iii) > (i)> (ii)

Acidity is directly proportional to oxidation number. As the oxidation number of S, P and Cl in H₂SO₃ , H₃PO₃ and HCIO₃ is +4, +3, +5 respectively. So decreasing order of acidity will be (iii) > (I) > (ii)
