Electrons flow from which electrode to which electrode in a galvanic cell?

Electrons flow from which electrode to which electrode in a galvanic cell?

• A. Cathode to Anode
• B. Anode to Cathode
• C. Anode to Electrolyte
• D. Cathode to Cathode

Answer: (B)

In a galvanic cell, oxidation happens at the anode and reduction happens at the cathode. Electrons are produced at the anode and travel through the external circuit to the cathode. So the actual flow of electrons is from the anode to the cathode. Remember, the conventional current (positive charge flow) moves in the opposite direction, from the cathode to the anode, through the external circuit. For a real example like a zinc-copper cell, zinc is the anode and loses electrons, which then move to the copper electrode (the cathode) where reduction occurs.
