Question

How to identify which reaction is taking place in anode and cathode?

Answer 1

Electrons always flow from the anodeto the cathode or from the oxidation half cell to the reduction half cell. In terms of Eocell of the half reactions, the electrons will flow from the more negative half reaction to the more positive half reaction.

Answer 2

Remember

REDCAT - REDuction is at CAThode

LOAN - Oxidation is at ANode
