Question

V2O3 and V2O5 which is better oxidizing agent and why

Answer 1

Explanation:

As we move down the group, lower oxidation states become more stable than higher ones due to inert pair effect. Hence, Pb(II) is more stable than Pb(IV). This is why PbO

2

has a high tendency to accept electrons and convert into PbO. Therefore, it acts as a strong oxidising agent.
