why we consider anode as +ve pole and cathode as -ve pole in electrolytic cell but in electrochemical cell anode is taken as -ve while cathode as +ve pole.please tell me sir b/c I am so confused.
on anode oxidation takes place. And on cathode reduction takes place . So it is not a rule that anode will be positive or negative . It is the rule that on anode oxid. wil take place . And on cathode red .
