Question

The E^o for Cl₂/Cl^- is +1.36 V, for I₂/I^- is +0.53V for Ag⁺/Ag is +0.79V, Na⁺/Na is -2.71V and for Li⁺/Li is -3.04V. 

Arrange the following ionic species in decreasing order of reducing strength:

I-,Ag,Cl-,Li,Na

Answer 1

Greater the high negative E^o value of element greater is the reducing strength of species. 

So, decreasing order of reducing strength is-

Li > Na > I⁻ > Ag > Cl⁻
