1.	On the basis of the following data, explain why Co(III) is not stable in aqueous solution? `Co^(3+)+e^(-)toCo^(2+),E^(@)=+1.82V` `2H_(2)OtoO_(2)+4H^(+)+4r^(-),E^(@)=1.23V`.
Answer» Adding the two half reaction, EMF comes out to +ve. This means that Co(III) in aqueous solution has the tendency to change to Co(II). Hence, Co (III) is not stable in aqueous solution.
