Guida verificata passo dopo passo1
Understand the basic components of an electrolytic cell: anode, cathode, external circuit, and electrolyte.
Recall the definition of oxidation: it is the loss of electrons by a species.
Identify where oxidation typically occurs in electrochemical cells: oxidation occurs at the anode.
Differentiate between the anode and cathode: in an electrolytic cell, the anode is the positive electrode where oxidation occurs, while the cathode is the negative electrode where reduction occurs.
Conclude that in an electrolytic cell, oxidation occurs at the anode, not at the cathode, external circuit, or in the electrolyte.
