Therefore, we chose those colors to represent SAAC. However, each type of cancer has its own color, and these are listed below:
Reaction of iron with the halogens. Iron reacts with excess of the halogens F2, Cl2, and Br2, to form ferric, that is, Fe(III), halides. This reaction is not very successful for iodine because of thermodynamic problems. The iron(III) is too oxidizing and the iodide is too reducing.
In the most known Landolt's clock reaction, potassium iodate and sulfite reacts with each other according to the clock mechanism to yield iodine, which than reacts with starch producing a dark blue colored complex. Various combinations of reactants that follow the clock mechanism are described in this section.
