In ancient Mesopotamian irrigation systems using bronze components, which electrochemical process accelerates corrosion in brackish water?

💡 Explanation

When dissimilar metals like bronze (copper-tin alloy) and iron are submerged in brackish water (electrolyte), galvanic corrosion occurs because the less noble metal (iron) corrodes preferentially, protecting the bronze. Therefore galvanic corrosion results, rather than oxidation, erosion, or stress cracking which require different environmental or loading conditions.
