Electrochemistry — Chemistry STD 12 Science — Question

1. Anode and cathode respectively.

Explanation:
Oxidation occurs at the electrode termed the anode and reduction occurs at the electrode called the cathode. In both galvanic and electrolytic cells, oxidation takes place at the anode and electrons flow from the anode to the cathode. and reduction takes place at cathode. The anode of an electrolytic cell is positive (cathode is negative), since the anode attracts anions from the solution.
