Melting Point: 1084.62 °C
Boiling Point: 2562 °C
- reacts with the oxygen in the air to create copper oxide
- poisonous in large amounts
- does not react with water
- corrodes when exposed to air
Copper can form a variety of compounds using the copper ions copper (I) and copper (II).
Copper carbonate (green layer) is found on old construction such as the Statue of Liberty.
Copper reacts with acid.
- Copper chloride (CuCl2)
- Copper cyanide (CuCN) - electroplating
- Cuprous chloride (CuCl) - absorbs carbon dioxide
- Hydrated copper sulfate (CuSO4·H2O)
Copper chloride CuCl2
Copper cyanide CuCN
Ionic bond, used as a catalyst in electroplating copper
Cuprous copper CuCl
Ionic bond, absorbs carbon dioxide
2 stable isotopes and 27 radioisotopes, most with half-lives under a minute
Cu-67 is the most stable, half-life of 2.6 days
Cu-54 is the least stable, half-life of 75 ns
Copper isotopes undergo beta decay and fission
Adding heat to the Cu and HCl reaction will speed up the reaction
Heat is given off in the reaction between copper and nitric acid
Types of Reactions
Reduction and Oxidization: Copper and nitric acid reaction, copper is oxidized while nitrogen is reduced
Pressure and Volume
The larger the amount of copper the lower the pressure.
