Which of the following pairs of transition metal ions are the stronger oxidising agents in aquesous solutions

Options

A. `V^(2+)` and `Cr^(2+)`
B. `Ti^(2+)` and `Cr^(2+)`
C. `Mn^(2+)` and `Co^(3+)`
D. `V^(2+)` and `Fe^(2+)`

Answer

C

Explanation

Oxidising agents are those which oxidise other compounds and get reduced themselves.
`Mn^(3+)` and `Co^(3+)` can act as a stronger oxidising agents because their least oxidation state to +2 oxidation state hence act as strong oxidising agents.
