← HistoryWhich reaction limits bronze implement durability in submerged Mesopotamian archaeological sites?
A)Dezincification causing structural weakening
B)Graphitic corrosion forming conductive layers
C)Pitting corrosion accelerating crack formation
D)Galvanic corrosion releasing copper ions✓
💡 Explanation
When submerged, galvanic corrosion occurs because bronze and iron (if present) form electrochemical cells in the electrolyte, leading to preferential oxidation of one metal and release of copper ions into the surrounding water. Therefore, galvanic corrosion results rather than dezincification, graphitic, or pitting corrosion which require different alloy compositions or environmental conditions.
