    why does vanadium have maximum observed oxidation state of +5 while for Co the maximum observed oxidation state is +3? why are solutions of chromium(2) acidic??? :confused: :confused:

    What would be the place to start, when looking for an answer to this? Should there be any reason for V and Co to have the same oxidation states? (In any case, Co(+4) exists too, such as in the fluoride, CoF4).
