Sodium Thiosulphate 25kg

Sodium thiosulfate (Na2S2O3) is an inorganic compound that is commonly used as a photographic fixer, as well as in medical and industrial applications. It is a white crystalline powder that is soluble in water and has a mild odor. In photography, sodium thiosulfate is used to remove unexposed silver halide from photographic prints and negatives, making the image permanent. In medicine, it is used as an antidote for cyanide poisoning, and in industrial applications, it is used as a reducing agent, a dechlorinating agent, and in water treatment processes.



Sodium thiosulfate has several major uses, including:

  1. Photography: Sodium thiosulfate is commonly used in photographic processing as a fixer. It is used to dissolve unexposed silver halide from photographic emulsions, thereby making the image permanent.
  2. Medical applications: Sodium thiosulfate is used in the treatment of cyanide poisoning. It reacts with the cyanide ion to form thiocyanate, which is less toxic and can be excreted by the body. It is also used in the treatment of calciphylaxis, a rare but serious condition in which calcium accumulates in the small blood vessels of the skin.
  3. Industrial applications: Sodium thiosulfate is used as a reducing agent in various industrial processes, such as the production of dyes and pharmaceuticals. It is also used as a dechlorinating agent in the treatment of wastewater and as a component of certain metal cleaners.
  4. Analytical chemistry: Sodium thiosulfate is used in several analytical chemistry applications, including iodometric titrations and as a reducing agent in quantitative analysis.
  5. Horticulture: Sodium thiosulfate is used in horticulture as a source of sulfur for plants. It can be used as a foliar spray or as a soil amendment to correct sulfur deficiencies in plants.

Overall, sodium thiosulfate is a versatile and important compound with a wide range of applications in various fields
