Which statement about anodic metals is true?

Anodic metals are characterized as being more active in electrochemical terms, which means they have a higher tendency to oxidize and lose electrons. This activity makes them less stable in environments that promote corrosion, leading them to corrode more easily compared to cathodic metals, which are more resistant to corrosion.

In marine settings, where various elements and electrolytes can contribute to corrosion, understanding the behavior of anodic metals helps in selecting materials and design strategies that mitigate corrosion risks. The active nature of anodic metals can be harnessed in sacrificial anode applications, where they corrode preferentially to protect other important structures or components from corrosion.

Conversely, the other statements do not accurately reflect the properties of anodic metals: they certainly do not resist corrosion; they can conduct electricity well because they lose electrons, and while some anodic metals are used strategically to provide protection, they are not preferentially selected for corrosion resistance due to their inherent tendency to corrode more readily.
