SATHEE: Equilibrium Question 270

Equilibrium Question 270

Question: Arrange the acids (I) $H_{2} S O_{3}$ (II) H3PO3 and (III) HClO3 in the decreasing order of acidity [UPSEAT 2001]

Options:

A) I > III > II

B) I > II > III

C) II > III > I

D) III > I > II

Show Answer

Answer:

Correct Answer: D

Solution:

Acidity is directly propotional to oxidation number. As the O.No. of S, P and Cl in $H_{2} S O_{3}, H_{3} P O_{3}$ & $H C l O_{3}$ is +4, +3 & +5 respectively so decreasing order of acidity will be III > I > II.
