Description

Used as a redox titrant in iodometry for TMAR chlorine determination according to SERES. Sodium Thiosulfate, 0.01M, Chem-Lab is a solution of 2.482g Na2S2O3·5H2O per 1L H2O. It is an inorganic compound with an excellent shelf life.

The thiosulfate anion reacts stoichiometrically with iodine in aqueous solution. Due to the quantitative nature of this reaction, sodium thiosulfate is used as a redox titrant in volumetric analysis and is a component of iodine clock experiments. It can be used to measure the oxygen content of water and to estimate the concentration of certain compounds in solution (hydrogen peroxide, chlorine). It also has many medicinal uses.
