Copper has a free electron in its outer orbital shell of electrons that easily takes part in oxidation-reduction reactions (which also makes the metal a good conductor). However, it reacts vigorously with steam: magnesium + steam → magnesium oxide + hydrogen Here are the equations for this reaction: copper + oxygen → copper oxide In this reaction, copper is oxidized to its +2 oxidation state while nitric acid is reduced to nitrogen dioxide. So, the hot copper sulfate solution can be more concentrated. Why would you not use a metal such as magnesium to make water pipes? There are some distinctive possibilities. All Rights Reserved.

Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium sulfate, or magnesium sulfate) with a copper anode. Aluminum does not appear to react with water because an outer layer of aluminum oxide (Al 2 O 3) solid forms and protects the rest of the metal. As a … The products are potassium nitrate, iodine, nitrogen monoxide and water. When a copper tube is initially filled with a hard water salts deposit on the wall and the copper slowly reacts with the water producing a thin protective layer of mixed corrosion products and hardness scale.
