In an electrochemical cell, which region is where metal is lost and electrons are produced?

• A. Cathode
• B. Electrolyte
• C. Anode
• D. Metallic path

Answer: (C)

The region is where oxidation happens. Oxidation is the loss of electrons, so the electrode where the metal loses electrons and dissolves into ions is the anode. In this spot, electrons are produced and flow out through the external circuit toward the other electrode. The cathode, in contrast, is where reduction occurs (gaining electrons). The electrolyte is just the ion-containing medium that supports charge balance, and the metallic path is the conductor linking the electrodes, not a site of metal loss. So, the anode is the area where metal is oxidized and electrons are produced.
