PbO_(2) is a stronger oxidising agent than SnO_(2).

1.	PbO_(2) is a stronger oxidising agent than SnO_(2).
Answer» Solution :In `PbO_(2)` and `SnO_(2)`, BOTHLEAD and tin are present in `+4`-oxidationstate. But due to STRONGER inert pair EFFECT,`Pb^(2+)`ions is more stable than `Sn^(2+)`ions . In other words, `Pb^(4+)` ions i.e. `PbO_(2)`,is more easily reduced to `Pb^(2+)`ions than `Sn^(4+)`ions are reduced to`Sn^(2+)` ions. Thus, `PbO_(2)` acts a strongeroxidising agent than `SnO_(2)`.
