Copper will not react with hydrochloric acid. For this type of reaction to occur, the reduction potential of the reactant receiving the electrons must be lower than the reduction potential of the reactant giving up electrons. Why, and why does thi...
copper can be readily customized. This is achieved by alloying: making a new metal out of two or more different metals. The most well-known copper alloy families are brass (copper-zinc), bronze (copper-tin) and copper-nickel. These actually represent families of alloys, all made by varying the amount of specific alloying elements. Alloys can be ...
