Is copper reactive with air
WebAluminium + copper(II) sulfate → copper + aluminium sulfate; Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. This allows a simple exchange reaction with the copper(II) sulfate. The protective oxide layer forms instantly the aluminium is exposed to the air. WebThis occurs because of a slow chemical reaction between the metal surface and the oxygen in air. The reaction produces a coating of metal oxide on the surface of the metal. copper …
