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

Options

A. `V^(2+)andCr^(2+)`
B. `Ti^(2+)andCr^(2+)`
C. `Mn^(3+)andCo^(3+)`
D. `V^(2+)andF^(2+)`

Answer

C

Explanation

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