Thiosulfate USP
Contains
not less than 99.0 percent and not more than 100.5 percent of Na2S2O3,
calculated on the anhydrous basis.
Packaging and storage— Preserve in tight containers.
Identification—
A: To a solution (1 in
10) add a few drops of iodine TS: the color is discharged.
B: A solution (1 in 10)
responds to the tests for Sodium and for Thiosulfate.
Water— Dry about 1.0 g,
accurately weighed, in vacuum at 40 o to 45o for 16 hours:
it loses between 32.0% and 37.0%
of its weight.
Calcium— Dissolve 1 g Sodium Thiosulfate in 20 mL of water, and add a few mL of ammonium oxalate TS: no turbidity is produced.

Uses of Sodium Thiosulfate
Pentahydrate or Sodium Thiosulphate Pentahydrate
Sodium thiosulfate is used in
Iodometry.
It is used for Gold
Extraction.
It is used in Analytical
Chemistry.
It is an antitode to Cyanide
poisioning.
It is a component in hand warmers and
other chemical heating pads that produce heat by exothermic
crystallization of a super cooled solution.
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 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.
It 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 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.
It 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.
