Astronauts get the oxygen they need through electrolysis. 1 and the circuit diagram in Fig. Electrolysis refers to the use of electricity to drive a chemical reaction that would not normally occur on its own. As the zinc atoms lose electrons, they become positively charged zinc ions, and move into the solution. A Hoffman electrolysis apparatus collects the two gases separately and shows the 2 to 1 ratio nicely. Before we go further, remember that rust is iron oxide -- iron and oxygen. For rust removal, the rusty part (cathode) is placed in a bath (electrolyte) along with another chunk of metal (anode).
