What is the primary function of an anode in an electrochemical cell?

• A. To attract cations
• B. To repel cations
• C. To produce heat
• D. To ensure grounding

Answer: (A)

The primary function of an anode in an electrochemical cell is to attract cations. In an electrochemical cell, the anode is where oxidation occurs, and as the process unfolds, positive ions (cations) are generated due to the loss of electrons. These cations move through the electrolyte towards the cathode, driven by the electric potential created in the cell. The anode serves as the site of this positive charge buildup, facilitating the flow of cations in the electrochemical process. This fundamental role is crucial in both galvanic (voltaic) and electrolytic cells, as it supports the overall functionality of the electrochemical system.
