← HistoryWhich consequence results when archaeologists unearth bronze tools after extended burial in saline soil?
A)Forming cuprite through dealloying enhancement✓
B)Exhibiting ductile fracture from hydrogen embrittlement
C)Transforming to austenite during recrystallization annealing
D)Passivating via creation of chromium oxide film
💡 Explanation
When bronze tools are buried in saline soils, dealloying is accelerated because chlorides enhance the electrochemical dissolution of tin, leaving a copper-rich surface that reacts to form cuprite (Cu2O). Therefore, cuprite formation results, rather than ductile fracture, austenite transformation, or passivation, which require very different environments and alloy compositions.
