- These reactions depend on the ability of the reducing sugar to convert cupric sulfate to cuprous oxide with a resulting color change.
- Without chromium, however, this alloy is vulnerable to corrosion attack in reducing acids when oxidizing salts such as ferric or cupric chloride are present, even in the parts-per-million range.
- Briefly, the washed hair was digested in an alkaline solution, complexed by cysteine, urea, and cupric ion, then acidified with sulfuric acid.
- The oxidizing fluxes usually include cupric oxide or manganese dioxide, which decompose at copper alloy melting temperatures to generate the oxygen required.
