A BREATH OF FRESH AIR Lab Activity
 
Chemistry

Key Topic: Electrolysis

One part of the Environmental Control and Life Support System on the International Space Station is production of breathable oxygen for the crewmembers. In this lab activity Students will learn about the electrolysis process that is used on the ISS to produce oxygen and will then perform their own electrolysis.

Students will
  • construct an electrolytic cell;
  • determine the number of moles and mass of oxygen produced;
  • determine the number of electrons transferred; and
  • compare their experimental electrolytic cell to the Oxygen Generator System used on the International Space Station.
