Redox Reaction
A redox reaction is a combination of reduction and oxidation reactions. In reduction, one of the atoms in a compound or ion earns electrons. In oxidation, one of the atoms in a compound or ion loses electrons. The reaction between triiodide ions and thiosulfate ions is a redox reaction. In the reaction, the triiodide ion is reduced to the iodide ion. The thiosulfate ion undergoes oxidation to the tetrathionate ion.
