Neither.
Copper oxide is neither an acid nor an alkali. It is considered a basic oxide because it reacts with acids to form salts and water.
Copper oxide is not considered an alkali. Alkalis are bases that dissolve in water to produce hydroxide ions, while copper oxide is a basic oxide that does not dissolve in water to form hydroxide ions.
Copper (I) Oxide or Cuprous Oxide
Cuprous oxide or copper(I) oxide. This is copper in oxidation state '1'.
CuO = Cupric Oxide Cupric = Cu2+ and is not Cu The correct answer would be CuO = Copper Monoxide Copper (II) oxide is the name of the compound CuO.
The correct chemical formula for copper oxide is Cu2O for copper(I) oxide (cuprous oxide) and CuO for copper(II) oxide (cupric oxide).
When copper is burned in the presence of air, it forms copper oxide. Copper oxide can exist in different forms, such as copper(I) oxide (Cu2O) or copper(II) oxide (CuO), depending on the conditions of the reaction.
Magnesium + copper oxide --> magnesium oxide + copper
copper oxide
copper oxide---> copper + oxygen
Copper oxide
Since there are two valence states for copper, Cu+ and Cu2+, there are two compounds formed from copper and oxygen:Copper (I) Oxide = Cu2O (equation: 4Cu + O2 --> 2Cu2O)Copper (II) Oxide = CuO (equation: 2Cu + O2 --> 2CuO)
