`Mn^(2+)` can be converted into `Mn^(7+)` by reacting with

A

`SO_(2)`

B

`Cl_(2)`

C

`PbO_(2)`

D

`SnCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C

Strong oxidizing agents such as `PbO_(2)` or sodium bismuthate `(NaBiO_(3))` oxidize `Mn^(2+)` to `MnO_(4)^(-)` or `Mn^(7+)`.
