Stress corrosion of copper in sulfide solutions: Variations

The predicted corrosion potential is about 200 mV lower than the equilibrium potential for a 1.0 µM concentration of Cu 2 S(HS) 2 2−, which is the most stable form of dissolved copper at pH 12. Very low concentrations of dissolved copper and no solid corrosion products can form at pH-values higher than pH 12 at 1.0 atm H 2 .
