It is because of inability of ns 2 electrons of the valence shell to participate in bonding that :

Sn 2+ is reducing while Pb 4+ is oxidising

Sn 2+ is oxidising while Pb 4+ is reducing

Sn 2+ and Pb 2+ are both oxidising and reducing

Sn 4+ is reducing while Pb 4+ is oxidising

Text Solution

Verified by Experts

The correct answer is:

Order of stability

Sn 2+ < Sn 4+

Pb 2+ > Pb 4+

So Sn 2+ reacts as a reducing agent and Pb 4+ reacts as an oxidising agent.
