The fresh water nails are covered in a reddish patina, while the salt water nails are covered in a powder green coating, which has also settled on the bottom of the container in keeping the nails in. Since the mole ratio is effectively 1:1, the empirical formula is Cu1O1 or CuO 6. Copper oxidation, on the other hand, prevents further oxygen exposure and corrosion by solidly adhering to the metal's surface. If only one atom of copper bonds to an oxygen molecule, it is called cupric oxide. 2CuO + H 2 → 2Cu + H 2 O Procedure 1. The oxide density is 6.31 g mL -1.

The chemical formulae of these compounds are Cu2O and CuO, respectively. Weigh the reduction tube empty. When copper is exposed to water molecules (two hydrogen, one oxygen), this free electron is transferred to a neighboring oxygen atom, bonding it into a molecule. It acts as a good corrosion resistance, due to reactions at the surface between the copper and the oxygen in air to give a thin protective oxide layer. CuO is sometimes added to clay glazes as a pigment. If two copper atoms bond to an oxygen atom, it is cuprous oxide. This layer is known as the patina.
