Electrolysis of Water: Sulfuric Acid Solution
The reaction shown in the movie below comes from the Chemistry Comes Alive! (CCA!) video collection. CCA! is published by the Journal of Chemical Education Software, Division of Chemical Education, Inc., American Chemical Society.

About This Movie
Two cylinders containing sulfuric acid dissolved in water are connected with tubing. When electricity passes through the system, oxidation occurs at one electrode and reduction at the other. Electrolysis of the water generates hydrogen gas at one electrode and oxygen at the other. The role of the sulfuric acid is to allow transfer of charge from one platinum electrode to the other. As the time lapse shows the volume of gas collected at each electrode differs. The volume of gas generated at each electrode can be determined from the volume readings on the cylinders. When gas from the left cylinder is collected in a test tube and a lighted match is brought near it the gas ignites with a barking noise indicating hydrogen. When a glowing match is brought near gas from the right cylinder the match burns brightly indicating the presence of oxygen.
