Which of the following can be oxidized further with a strong oxidising agent? S O 2 M n O 2 A l 2 O 3 C r O 3

Options

A. `SO_2`
B. `MnO_2`
C. `Al_2 O_3`
D. `CrO_(3)`

Answer

A, B

Explanation

A)`SO_2` can be oxidized to S`O_3` B) `MnO_2` can be oxidized to either` MnO_(4)^(2-)` or `MnO_(4)^(-)` C) In`Al_2 O_3 `Al(III) is already in its highest oxidation state, can.t be oxidized further D) In `CrO_3, Cr(VI)` is already in its highest oxidation state, can.t be oxidized further
