Uses
It is used in Idometry, Gold Extraction, Medicine and several other things.
Sodium thiosulfate 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 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 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.
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 thiosulphate is used in bacteriological water assessment.
It is used in the tanning of leather.
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.
It is used 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.
