Sodium Thiosulfate USP FCC ACS AR Analytical Reagent
Sodium Thiosulphate BP ACS AR Analytical Reagent
Sodium thiosulfate (Na2S2O3), also spelled Sodium thiosulphate, or thio sulphate is a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3•5H2O. Sodium thiosulfate or Sodium thiosulphate is an efflorescent, monoclinic crystalline substance also called sodium hyposulfite or “hypo”.
The thiosulfate anion is tetrahedral in shape and is notionally derived by replacing one of the oxygen atoms by a sulfur atom in a sulfate anion. The S-S distance indicates a single bond, implying that the sulfur bears significant negative charge and the S-O interactions have more double bond character. The first protonation of thiosulphate occurs at sulfur.
Thiosulfate anion characteristically reacts with dilute acids to produce sulfur, sulfur dioxide and water
Na2S2O3 + 2HCl → 2NaCl + S + SO2 + H2O
This reaction is known as a clock reaction, because when the sulfur reaches a certain concentration the solution turns from colourless to a pale yellow. This reaction has been employed to generate colloidal sulfur. When the protonation is conducted at low temperatures, H2S2O3 (thiosulfuric acid) can be obtained. It is a strong acid pKa
Iodometry
In analytical chemistry, the most important use comes from the fact that the thiosulphate anion reacts stoichiometrically with iodine, reducing it to iodide as it is oxidized to tetrathionate:
2 S2O32−(aq) + I2(aq) → S4O62−(aq) + 2 I−(aq)
Due to the quantitative nature of this reaction, as well as the fact that Na2S2O3•5H2O has an excellent shelf-life, it is used as a titrant in iodometry. Na2S2O3•5H2O is also a component of iodine clock experiments.
This particular use can be set up to measure the oxygen content of water through a long series of reactions. It is also used in estimating volumetrically, the concentrations of certain compounds in solution (hydrogen peroxide, for instance), and in estimating the chlorine content in commercial bleaching powder and water.
Gold extractionSodium thiosulphate is one component of an alternative lixiviant to cyanide for extraction of gold. It forms a strong complex with gold I) ions, [Au(S2O3)2]3-. The advantage of this approach is that thiosulfate is essentially non-toxic and that ore types that are refractory to gold cyanidation (e.g. carbonaceous or Carlin type ores) can be leached by thiosulphate. Some problems with this alternative process include the high consumption of thiosulfate, and the lack of a suitable recovery technique, since [Au(S2O3)2]3- does not adsorb to activated carbon, which is the standard technique used in gold cyanidation to separate the gold complex from the ore slurry.
Analytical chemistrySodium thiosulphate is also used in analytical chemistry. It can, when heated with a sample containing aluminum cation, produce a white precipitation:
2Al3+ + 3S2O32- + 3H2O → 3SO2 + 3S + 2Al(OH)3
MedicalSodium thiosulfate is used as an antidote to cyanide poisoning. Thiosulphate acts as a sulfur donor for the conversion for cyanide to thiocyanate (which can then be safely excreted in the urine, catalyzed by the enzyme rhodanase.
Sodium thiosulphate has also been used as treatment of calciphylaxis in hemodialysis patients with end-stage renal disease.
Other uses
Sodium thiosulfate or Sodium thiosulphate is used as a component in hand
warmers and other chemical heating pads that produce heat by exothermic
crystallization of a super cooled solution.
Sodium thiosulfate or Sodium
thiosulphate is used in Bleach.
In pH testing of bleach
substances.
To de-chlorinate tap water for
aquariums or treat effluent from waste water treatments prior to release
into rivers. The
amount of Sodium thiosulfate or Sodium
thiosulphate required can vary with the pH of the water. A
range of approximately 2 to 7 parts sodium thiosulfate to neutralize one
part chlorine is generally suggested. To neutralize 1 liter of a 200 ppm
chlorine solution, approximately 0.4 - 1.4 grams of sodium thiosulfate would
be required.
Sodium thiosulfate or Sodium
thiosulphate is used to lower chlorine levels in
swimming pools and spas following super chlorination.
It is used to remove iodine stains, e.g.
after the explosion of nitrogen triiodide.
Sodium thiosulfate or Sodium
thiosulphate is used in bacteriological water
assessment.
It is used in the tanning of leather.
Melted sodium thiosulfate is very easy
to overcool to room temperature and when crystallization is forced, the
sudden temperature jump to 48.3°C can be experienced by touch. It is
used in phase change material.
Sodium thiosulfate or Sodium
thiosulphate is used in paper industry.
It is used in medicine and as disinfectant.
A low amount can be found in natural hot springs water, but
they do have trace sodium sulfide too, which is why it can used to treat
skin problems and some bathe in it to relieve them of skin problems,
rheumatism, although indirectly.
It is
systemically for cyanide or arsenic poisoning and topically as an
antifungal.
It is used in electroplating.
As part of patina recipes for
copper alloys.
Often used in pharmaceutical preparations as an
anionic surfactant to aid in dispersion.
