Metal > CopperCu - Copper As the transition metal copper can be found pure in nature, it was known to the ancients. Originally popular for its high malleability, the extremely high electrical conductivity of copper (second only to silver) makes it the conductor of choice for most wires. Our students observe the dehydration of copper sulfate pentahydrate, determine the composition and electrochemistry of copper salts, and may assay copper ore. The chemistry and society class takes a field trip to a copper mine.
