With the Copper Test Tube Oxidation–Reduction Chemical Demonstration Kit, take a “clear” test tube, add a few drops of chemical solutions, swirl and place it in hot water. Before students’ very eyes, they will see copper develop.
Take a test tube that “appears” to be absolutely clear, add a few drops of different chemical solutions, swirl the test tube around and place it in hot water. Before your students’ very eyes, they will see a beautiful film of copper develop and deposit on the test tube glass. Teacher Demonstration Notes included.
Concepts: Oxidation–reduction. Time Required: 20 minutes Note: Perform this demonstration in a fume hood or well-ventilated lab.
