Question

Why is the electrode potential of Anode taken a negative in electrochemical cell while it is taken a positive in electrolytic cell?​

Answer 1

The anode is the electrode where oxidation (loss of electrons) takes place; in a galvanic cell, it is the negative electrode, as when oxidation occurs, electrons are left behind on the electrode. ... This is why the cathode is a positive electrode; because positive ions are reduced to metal atoms there.
