Which electrochemical consequence results when dissimilar metals form a galvanic couple immersed in seawater?

💡 Explanation

When dissimilar metals form a galvanic couple in seawater, electron transfer occurs because of differing reduction potentials, leading to electrolytic corrosion where the more active metal (anode) corrodes faster. Therefore, accelerated corrosion occurs at the anode, rather than passivation, inhibition or uniform dissolution, which require noble surfaces or applied potentials.
