1
(Ag+/Ag) is the more strongly reducing as compared to (Zn2+/Zn) and (Ca2+/Ca) is least reducing
2
(Ag+/Ag) is the less strongly reducing as compared to (Zn2+/ Zn) and (Ca2+/Ca) is most reducing
3
(Zn2+/Zn) is more strongly reducing than (Ca2+/Ca) and (Ag+/Ag) is most strongly reducing
4
All redox couples have similar reducing ability
