An Experiment in Alchemy: Copper to Silver to Gold
How exciting would it be for your chemistry class to produce their own "gold"? This experiment allows pupils to witness the chemical reaction of copper pennies as they react with zinc and sodium hydroxide to produce "gold" tokens. It is...
Chymist
An Experiment in Alchemy: Copper to Silver to Gold
Use chemistry to change pennies into gold coins! The experimental procedure leads learners through the process of changing copper pennies to silver and then to gold. They record the mass of each coin through every step of the experiment.
