銅的化學問題F.3

Copper in moist air slowly acquires a dull green coating because its top layer has oxidised with the air. The green material is a 1:1 mole mixture of Cu(OH)2 and CuCO3:2 Cu (s) + H2O (g) + CO2 + O2 → Cu(OH)2 + CuCO3 (s)Basic copper(II) carbonate occurs naturally as maachite (Cu2(OH)2CO3) and azurite (Cu3(OH)2(CO3)2).

The green material is 銅綠: a mixture of Cu(OH)2 and CuCO3:

2Cu ＋ O2 ＋ H2O ＋ CO2 = Cu2(OH)2CO3

銅綠是 Cu2(OH)2CO3

Chemical name in Chinese: 碱式碳酸铜
