← HistoryWhich risk increased due to tin leaching from high-arsenic bronze tools in the Bronze Age?
A)Reduced tool hardness and failure✓
B)Metallurgical cracking during casting
C)Corrosion from acidic soil exposure
D)Increased susceptibility bacterial degradation
💡 Explanation
When high-arsenic bronze corrodes in the soil, preferential leaching of the tin component occurs because oxides in the arsenic bronze leave the metal vulnerable during soil reactions, thereby reducing the overall tin content, directly reducing the alloys durability. Tools become easily fatigued. Thus weakening occurs, rather than cracking or corrosion with acidity or degradation requiring environmental factors.
