Chemistry Demonstration, Rainbow Electrolysis

Chemistry Demonstration, Rainbow Electrolysis

Study oxidation-reduction, electrolysis and acid-base reactions as Universal Indicator is added to an aqueous sodium sulfate solution. When two carbon electrodes are connected to a battery and placed in the solution, a rainbow of colors forms as the water is electrolyzed. There are enough materials to complete the demonstration 5 times.
