* Pb results are most unreliable

Which is the strongest oxidizing agent in the table?

B. Which is the strongest reducing agent in the table?

Answer 1

A) we know that

oxidizing agent is the one which undergoes reduction

and

reducing agent is the one which undegoes oxidation

now

the one which lies on the top of the reduction potential table is the best reducing agent

and

the one which lies at the bottom of the reduction potential table is the best oxidzing agent

now

for the given elemens

the order is

1) Mg   Eo = -2.37

2) Al   Eo = - 1.66

3) Zn   Eo = -0.76

4) Sn   Eo = -0.13

5) Pb   Eo = -0.12

6) Cu   Eo = 0.34

So

Mg is the strongest reducing agent

and

Cu+2 is the strongest oxidizing agent
