Foiled Again - Aluminum Loses to Copper - Chemical Demonstration Kit
By: The Flinn Staff
Item #: AP5936
With the Foiled Again - Aluminum Loses To Copper Oxidation-Reduction Chemical Demonstration Kit, students study color changes, gas production, solid formation, and more. Students analyze catalysts in the redox battle of aluminum and copper.
Watch metallic copper appear instantaneously as aluminum foil is added to aqueous cupric chloride. Try adding aluminum foil to aqueous cupric sulfate—no copper forms and aluminum survives! Add a catalyst—copper appears and aluminum is foiled again! Students observe color changes, production of a gas, formation of a solid, and a drastic change in temperature. Students learn the crucial role of a catalyst with this visually dramatic demonstration—a true redox battle between aluminum and copper. Teacher Demonstration Notes included.Enough materials are included to perform the demonstration seven times.
Concepts: Oxidation-reduction, catalysis, single-replacement reactions.
Time Required: 15 minutes
Chemicals Provided: Aluminum foil, copper(II) chloride solution, copper(II) sulfate solution, sodium chloride solution.
