Outer electronic configuration of CO is 3d74s2.

Outer electronic configuration of CO3+is 3d64s0.

Now Co in CO3+state is not stable in aqueous solution. But Co is stable inCO2+state in water. This is the reason it likes to go from Co(III) to Co(II) state by gaining electrons or in other words, it gets reduced and acts as good oxidizing agent.



Thank You'
