Question

Relative Reduction Potential

Assuming standard conditions, and considering the table of standard reduction potentials for half-reactions, given in your text, rank the following species according to their relative strength as reducing agents. For example, the most powerful reducing agent would be given rank "1", and the least "6".

1 2 3 4 5 6  Fe²⁺
1 2 3 4 5 6  K
1 2 3 4 5 6  H₂O₂ (acidic half-cell solution)
1 2 3 4 5 6  Mn
1 2 3 4 5 6  Ag⁺
1 2 3 4 5 6  Ni

Note: 4,1,5,2,6,3 are not the correct set of answers

Answer 1

The correct sequence will be... 4,1,6,2,5,3.

And here is the explanation.
