Question

Which is the correct order of increasing oxidizing ability?



Pb²+ < Ni²+ < Cr³+ < Al³+

Al³+ < Cr³+ < Ni²+ < Pb²+

Cr³+ < Al³+ < Ni²+ < Pb²+

Ni²+ < Pb²+ < Al³+ < Cr³+

​

Answer 1

Explanation:

Metals are good reducing agents, while non-metals are good oxidizing agents. Further among halogens, metallic character increases as we move from top to bottom in a group, i.e., the oxidizing nature is I2<Br2<Cl2<F2.
