Why is thiosulphate added in the oxidation of iodide ions?

In this experiment my friendly was correct; it is very to determine if a mediocre is a redox eating based on oxidation numbers. The iodine clock reaction exists in several variations, which each involve iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch.
