Nitrogen Oxides and Acid Rain—Demonstration Kit
When nitrogen and oxygen—the two primary components of the air we breathe—combine under certain conditions, the results can be devastating. In this demonstration, nitrogen oxides are generated by the dissolution of copper in nitric acid and the resulting gases are bubbled into a larger container of water containing an indicator. As the water shifts from near neutral
to highly acidic, the color change is dramatic and unmistakable. And just when the reaction appears to be complete... a breathtaking surprise!
