The chemical reaction between iodine pentoxide and very fine iron powder. Both are mixed and ignited. During the reaction, Iron is oxidized to form iron oxide and iodine pentoxide is reduced to elemental iodine. 3I2O5 + 10Fe -> 3I2 + 5Fe2O3 ( @reaction

< Previous The reaction in this experiment is termed an iodine clock reaction because it is the molecular iodine (I2) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with the starch in the solution to form a complex Crystals are beautiful, but more beautiful are the processes of forming crystals. This film recorded the crystallization processes of 5 salts. We first added droplets of saturated salt solutions on glass slides. The evaporation of water initiated the crys Next >
