A galvanic series is a listing of metals in the order of their potential in a specific electrolyte.

• A. Galvanic series
• B. Electrochemical table
• C. Noble scale
• D. Potential sequence

Answer: (A)

The main idea is that this is a ranking of metals by their electrochemical potential in a specific electrolyte. That ordered list is called the galvanic series. It’s used to predict galvanic corrosion: when two metals are connected in an electrolyte, the metal lower in the series tends to act as the anode and corrode, while the metal higher in the series acts as the cathode. The potentials shift with different electrolytes, so the series is specific to the environment. Other labels like “electrochemical table,” “noble scale,” or “potential sequence” aren’t the standard name for this commonly used list in corrosion science, which is why the galvanic series is the best term.
