WebSep 26, 2014 · If you see galvanic cell reduction take place at the left electrode, so the left one is the cathode. ... While in electrolytic cell reduction takes place at the right electrode, …
WebSince the Gibbs energy is negative, the cell will function as a galvanic cell as written in the cell diagram and in which zinc will be oxidized and copper ions will be reduced. WebThe electrode at which oxidation takes place in a electrochemical cell is called the anode. The electrode at which reduction occurs is called the cathode. The identity of the cathode and anode can be remembered by recognizing that positive ions, or cations, flow toward the cathode, while negative ions, or anions, flow toward the anode.
