In a Daniell cell, when a Za electrode and a Cu electrode ane connected with a wire

Options

A. electrons flow from the Zn electrode to the Cu electrode through the wire
B. electrons flow from the Cu electrode to the Zn electrode through the wire
C. current flow from the Zn electrode to the cu electrode through the wire
D. electrons flow from the Zn electrode to the cu electrode through the cell

Answer

A

Explanation

Electrons are released (by oxidation) at the anode (Zn electrode ) and consumed (by reduction) at the cathode (Cu electrode). Therefore, electrons flow through thewire from anode to cathode, i.e., in all voltaic cells, the electrons flow spontaneously from the negative electrode to the positive electrode.
