Account for the following observations :
`PbO_2` is a stronger oxidizing agent than `SnO_2`.

Text Solution

Verified by Experts

In `PbO_2` and `SnO_2` both lead and the tin are present in +4 oxidation state but due to stronger inert pair effect, `Pb^(+2)` ion is more stable than `Sn^(+2)` ion. So `PbO_4` is stronger oxidising agent.
