What neutralizes copper oxide


Copper (II) oxide reacts with sulfuric acid to create water and copper (II) sulfate. This reaction could be classified as a double displacement or neutralization reaction. Copper oxide nanoparticles are highly toxic: a comparison between metal oxide nanoparticles and carbon nanotubes. The primary metals of concern in terms of galvanic corrosion contact with copper are aluminium and zinc. Significant differences in the thermal expansion rate between copper and these metals may cause additional problems. Also, avoid using copper and some brass fasteners with aluminium, zinc and most ferrous metal. Oxide copper–gold ores are usually accompanied by iron hydroxide slimes and various clay minerals. There are several deposits of this ore type around the world, some of which are located in Australia (Red Dome), Brazil (Igarape Bahia) and the Soviet Union (Kalima). Generally, copper (II) oxide is produced by reacting an acidic copper solution (CuCl2, CuSO4, or Cu(NO3)2) with a hydroxide (NaOH, KOH) or alkali carbonate to convert it to copper hydroxide (Cu(OH)2) or alkali copper carbonate (CuCO3·Cu(OH)2), followed by calcination at 250 to 800°C Other metals such as bronze and copper also undergo oxidation, leading to corrosion. So, the answer is NO; copper does not rust. However, it does corrode! Oxidation happens when copper is exposed to moisture and air. It forms a green compound called patina. This mixing of metal and oxygen produces copper oxide. Scientifically speaking, patina is the green or brown film that forms naturally on the surface of copper due to a series of chemical reactions. Copper develops a patina when exposed to oxygen and weathering over time.
