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.
