The passage of electricity in the Daniel cell when Zn and Cu electrodes are connected — Electrochemistry Chemistry Question

💡 Solution & Explanation

In a Daniel cell, electrons flow from the zinc anode to the copper cathode through the external wire. By convention, electric current flows in the direction opposite to electron flow, meaning it flows from the Cu electrode to the Zn electrode outside the cell. To complete the continuous circuit, the current must flow from the Zn electrode to the Cu electrode inside the cell via the salt bridge/electrolyte. Therefore, correct answer is B,C.
