Question
Arrange the following reducing agents in the order of increasing strength under standard state conditions. Justify the answer
|
Element |
Al(s) |
Cu(s) |
Cl(aq) |
Ni(s) |
|
Eo |
-1.66V |
0.34V |
1.36V |
-0.26V |
Solution
Cl < Cu < Ni < Al
Reason: Substances which have lower electrode potential are stronger reducing agents, while those which have high electrode potential are stronger oxidising agents.
