Electrolysis Practice Exam

In galvanic treatments, what role does the anode play?

1. Negative electrode

2. Positive electrode

3. Ground reference

4. Current stabilizer

The correct answer is: Positive electrode

In galvanic treatments, the anode serves as the positive electrode. This is significant because, during the process, oxidation reactions occur at the anode. In electrolysis, the anode is where electrons are drawn out of the electrolyte, making it positive relative to the cathode. This creates a flow of electricity that is essential for the treatment process, helping to stimulate the skin or tissue being treated. The selection of the anode as the positive electrode reflects its essential function in the overall electrochemical reaction that facilitates healing or enhancement during the galvanic treatment. The oxidation reactions at the anode are crucial for various electrotherapeutic applications, such as promoting circulation, tissue repair, or product penetration.
