Oxidation-Reduction, Stoichiometry, Electrochemistry
Maintaining a permanent human presence on the International Space Station requires a well organized and precise life support system, a part of which is the Oxygen Generator System. Students will learn about how the OGS produces breathable oxygen for the crew by converting wastewater from the ISS into oxygen and hydrogen through the process of electrolysis.
