As a mineral, it is known as tenorite.It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds. Note that the copper is still in the form of Cu+2, that is, it has not undergone oxidation or reduction. Copper(I) ions in solution disproportionate to give copper(II) ions and a precipitate of copper. The black copper oxide that is produced can be restored to original copper color through a reaction with hydrogen. The physical change you should observe is the copper-colored metal vanishing as the solution turns blue (from [Cu(H 2 O) 6 ] 2+ , the hexaaquacopper ion) and a brown gas (NO 2 ) is evolved. However, it is the hydrated form of the salt and has 5 water molecules. Join Yahoo Answers and get 100 points today.
