Which of the following reactions depict the oxidising behaviour of `H_(2)SO_(4)`?

A

`2PCl_(5)+H_(2)SO_(4) to 2POCl_(3)+2HCl + SO_(2)Cl_(2)`

B

`2NaOH + H_(2)SO_(4) to Na_(2)SO_(4) + 2H_(2)O`

C

`NaCl + H_(2)SO_(4) to NaHSO_(4) + HCl`

D

`2HI + H_(2)SO_(4) to I_(2) +SO_(2) +2H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
D
`overset(-1)(2HI)+overset(+6)(H_(2)SO_(4))to overset(0)(I_(2))+overset(+4)(SO_(2))+2H_(2)O`
Thus, `H_(2)SO_(4)` oxidises `HI` to `l_(2)`
