Question

I have a doubt that, why the "E0 = -1.18-1.51" as in many questions the greater value of E0 is consider as cathode and smaller value as anode . Then why here we have taken greater as anode and smaller as cathode??

Answer 1

Your doubt is doubtful ;

We decide anode and cathode by looking over reaction tooking place in respective electrode.

Oxidation at Anode .

Reduction at Cathode.

Hope you get all your query solved.
