Which of the following chemical reactions depicts the oxidizing behaviour of H₂SO₄?

Accepted Answer

2H{I^{ - 1}} + {H_2}\mathop {S{O_4}}\limits^{ + 6} \to I_2^0 + \mathop {S{O_2}}\limits^{ + 4} + 2{H_2}O

in this reaction oxidation number of

S

is decreasing from

+6

to

+4

hence undergoing reduction and for

HI

oxidation Number of

I

is increasing from

-1

to

0

hence undergoing oxidation therefore

{H_2}S{O_4}

is acting as oxidising agent.
