As the name suggests, Copper (II) Oxide consists of one copper atom (Cu) and one oxygen atom (O). The 'II' in its name signifies that the copper ion in this compound has a +2 oxidation state. This is a result of copper losing two of its electrons to oxygen, which is more electronegative. The compound's structure is characterized by a ...

Mix about 50% MS70 with 50% ammonia. Do this outside or in a well ventilated area as ammonia vapor is pretty potent and not good for you. If you have heavy mineral deposits on copper like verdigris (thick hard green mineral) it will dissolve it with soaking for a short period of time without damaging the copper.

The maximum conductivity of ETP copper occurs at approximately 200 ppm of oxygen as shown in Figure 3. Consequently, oxygen content for ETP copper is generally in the range of 175 to 450 ppm. Lower oxygen values are usually avoided because of a propensity to hot cracking resulting from uncombined impurities.
