GOLD PENNIES???

September 30, 2011

Ms. Klein's chemistry classes are off to a shiny gold start...that is they have made shiny "gold "pennies. During their study of mixtures, chemistry students plated zinc on to the outside of pennies. The pennies were then heated until the turned a bright gold color. Has the chemistry class found away to make gold? Unfortunately, the answer is no. They did learn that when zinc and copper are mixed, the alloy brass is formed.
