Why is Bi (V) a stronger oxidant than Sb (V)?

Text Solution

Verified by Experts

As we go down the group, +3 oxidation state gets more stable than +5 oxidation state due to inert pair effect. Bi (V) will take up two electrons to change into Bi (III) and thus behave as oxidant. In the case of Sb (V), conversion from +5 state to +3 will not occur readily.
