Copper

Chemical Properties:•When copper reacts to oxygen in the air, verdigris is created on top of the copper, which covers and protects the copper beneath it, instead of creating rust.•Reacts to different sulphides and then creates copper sulphides.•The Statue of Liberty is an example of copper being exposed to oxygen over a long period of time.

Societal Applications• Electrical generators and motors• Electrical wiring• Electronic goods such as TV sets, computers and phones• Motor vehicle radiators• Home heating and air-conditioning systems• Water pipes• Nutrients for animals and plants• Modern medicine for joint and ankle pains• Coins• Kitchen tools such as knives and frying pans• Construction of trains, cars and other vehicles• Fixtures in homes such as doorknobs or counters

How copper is obtainedIn order to get copper or copper ores from the earth’s crust, they have to be mined out. Ores contain some of the actual copper metal, and a lot of waste rock. The ore then has to be changed chemically into a metal, and so they get rid of all of the waste rock, and this is the process of reduction. Since copper’s reactivity is low, it is easy to extract from its ore. Then the impurities have to be extracted from their ore, and then so copper is purified through the process of electrolysis. Then the copper is shipped.

HistoryReports have found out that copper beads were found around 9000 B.C. in Northern Iraq. The exact date and name of the discoverer are unknown for this has been dated back to ancient times. Early societies, such as the Mesopotamians, Egyptians, and Native Americans have treated copper like gold or silver and have used it for decorations and ornaments around 5000 to 6000 years ago. The earliest production of copper from other early societies includes in China around 2800 B.C. and West Africa around 900 A.D. Did you know?Copper is the first metal ever to be used by man.
