|
|
|
The anode and cathode are both positive
|
|
|
The anode is positive and the cathode is negative
|
|
|
The anode and cathode are both negative.

Detailed explanation-1: -In a galvanic cell, the anode is negative and the cathode is the positive electrode and electrons move from anode to the cathode in the external circuit while in an electrolytic cell the anode is positive and the cathode is the negative electrode and electrons enter through the cathode and come out through the anode.
Detailed explanation-2: -Which statement correctly describes the 2 electrodes? The anode and cathode are both negative.
Detailed explanation-3: -The Anode is the negative or reducing electrode that releases electrons to the external circuit and oxidizes during and electrochemical reaction. The Cathode is the positive or oxidizing electrode that acquires electrons from the external circuit and is reduced during the electrochemical reaction.
Detailed explanation-4: -Here, the anode is positive and cathode is the negative electrode. The reaction at the anode is oxidation and that at the cathode is reduction. The electrons are supplied by the species getting oxidized. They move from anode to the cathode in the external circuit.
Detailed explanation-5: -During charge, the positive electrode is an anode, and the negative electrode is a cathode.
