HBr and HI can reduce sulphurie acid, HCI can reduced `KMnO_(4)` and HF can reduce…………….

A

`H_2SO_4`

B

`KMnO_4`

C

`K_2Cr_2O_7`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
D
Conc. `H_2SO_4` can oxidise HBr (or HI) to `Br_2` (or `I_2`). `KMnO_4//H^(+)` can oxidise HCl to `Cl_2`. However chemical oxidation of HF to `F_2` is not possible. This is because, fluorine has the highest reduction potential.
