What function does the anode serve in an electrochemical cell during oxidation?

In an electrochemical cell during oxidation, the anode serves the function of dissolving metal into the electrolyte. During the oxidation process, the metal at the anode loses electrons and transitions into positively charged ions, which enter the solution. This process is crucial in various applications, particularly in understanding corrosion mechanisms, where the metal substrate acts as an anode, leading to material degradation.

This dissolution contributes to the flow of electrons from the anode to the cathode, which is essential for maintaining the reaction cycle within the electrochemical cell. The positively charged ions formed at the anode can later be reduced at the cathode, completing the electrical circuit. Understanding the role of the anode in this capacity is vital for a coatings inspector, as it relates to the assessment of corrosion and the effectiveness of protective coating systems.
