Copper oxide, which is a compound from the two elements copper and oxygen. When copper is exposed to oxygen for a long period of time, it begins turning green. The green is Copper oxide.
Copper oxide can refer to
Sodium hydroxide is commonly used to make copper sulfate from copper oxide, which is insoluble in water. The reaction between copper oxide and sodium hydroxide forms copper sulfate and water.
Copper, sulfur, and oxygen can combine to form copper sulfate, which has the chemical formula CuSO4.
Sodium hydroxide (NaOH) is an insoluble base that can be used to make copper sulfate. When sodium hydroxide is added to a solution of copper sulfate, a blue precipitate of copper hydroxide forms. This precipitate can be filtered and then reacted with sulfuric acid to produce copper sulfate.
Copper oxide and sulfuric acid will react together to produce copper sulfate.
Copper plus oxygen react to form copper oxide. This reaction can be represented by the chemical equation: 4Cu + O2 → 2Cu2O.
They make magnesium oxide, MgO.
