摘要: Abstract The behaviour of copper has been studied in 0·5M NaCl and at pH values ranging from 2 to 10. In acid solution the anodic dissolution reaction leads formation Cu+ ions which can either form soluble complexes or precipitate as solid CuCl depending on their surface concentration. former situation holds free-corrosion potential presence oxygen. alkaline range behaves, low current densities (i.e. potentials), same way it does solutions; more potentials a protective layer Cu2O is formed.
