Elements like potassium and sodium have several different oxides. There is the oxide, the peroxide, and the superoxide. Potassium superoxide (KO2) was suggested to explain the results form Viking.
Hydrogen peroxide (H2O2) was also suggested to explain the Viking results. Unrelated to superoxides, there is a whole family of oxy-chlorine ions, going by the names of hypochlorite, chlorite, chlorate and perchlorate. They feature from one to four oxgen atoms bonded to each chlorine. Perchlorate has four oxygens. Perchlorates on Mars never got much attention before Phoenix. The non-detection of chlorine containing species by Phoenix requires an explanation. The paper linked above says that chlorine will react with the nickel which the oven was made of. |
