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» Solution :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. | |
