  • Chemische Eigenschaften Sodium thiosulfate, Na2S203·5H20, also known as sodium hyposulfite, hypo,andsodium subsulfite, is a white crystalline solid that has a melting point of 48 °C(118 °F). Water soluble,it is used as a fixing agent for photographic films, plates, and papers. Sodium thiosulfate is used in medicine, as a germicide, in manufacturing leather, as a mordant in dyeing, and for extracting silver from ore.
  • Physikalische Eigenschaften Anhydrous thiosulfate is a white powder; soluble in water; insoluble in ethanol.
    Sodium pentahydrate is a colorless, odorless, crystalline solid; density 1.69 g/cm3; decomposes around 50°C; effloresces in dry air above 33°C; very soluble in water and oil of turpentine; insoluble in ethanol.
  • Verwenden Sodium Thiosulfate is a sequestrant, antioxidant, and formulation aid that is a powder soluble in water. it can be used in alcoholic bev- erages at 5 ppm and in table salt at 0.1%. it is also termed sodium hyposulfite.
  • Verwenden Sodium thiosulfate (thiosulfate) Known simply as “hypo,” an abbreviated form of the incorrect form hyposulfite, this white crystal was made by boiling calcium thiosulfate with sodium sulfate. It is soluble in water and oil of turpentine but not in alcohol. The property of sodium thiosulfate to dissolve silver halides was discovered in 1819 by Sir John Herschel and was probably first used to fix photographic images by L. J. M. Daguerre. After Daguerre published its use in his 1839 manual W. H. F. Talbot finally used it to fix calotype negatives and silver chloride prints, although he continued to stabilize them with potassium iodide and sodium chloride presumably for the variety of colors possible. Sodium thiosulfate was the primary fixing agent throughout the 19th century and is still used today.
  • Verwenden Sodium thiosulfate is a common analytical reagent used in iodometric titration to analyze chlorine, bromine, and sulfide. Other uses are in bleaching paper pulp, bleaching straw, ivory, and bones, for removing chlorine from solutions, silver extraction from its ores, a mordant in dyeing and printing textiles, and as an antidote to cyanide poisoning.
    Another major application is in photography, where it is used as a fixer to dissolve unchanged silver salts from exposed negatives.
    Sodium Thiosulfate is used primarily as a medicament against cyanide poisoning, able to convert cyanide into thiocyanate, a reaction which is catalyzed by the enzyme Rhodanese. Antioxidant.
  • Definition ChEBI: An inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio.
  • synthetische Sodium thiosulfate is a common reducing agent. It reduces iodine to iodide anion forming sodium tetrathionate. This reaction is utilized in the so-called iodometric titration: 2S2O32ˉ + I2 → S4O62ˉ + 2Iˉ
    Sodium thiosulfate reacts with chlorine to form sodium bisulfate and hydrochloric acid. This reaction removes chlorine from aqueous solutions:Na2S2O3 + 4Cl2 + 5H2O → 2NaHSO4 + 8HCl
    Sodium thiosulfate reacts with hydrochloric acid, decomposing to sulfur and sulfur dioxide: Na2S2O3 + 2HCl → 2NaCl + S + SO2 + H2O.
  • Trademarks Sulfactol (Sterling Winthrop).
  • Allgemeine Beschreibung
    Sodium thiosulfate (Na2S2O3) can be obtained from Na2S2O3.10H2O by heating above 100 °C. It can be synthesized from sodium sulfate.
  • Hazard Use in foods restricted to 0.1%.
  • Sicherheitsprofil Moderately toxic by subcutaneous route. Incompatible with metal nitrates, sodium nitrite. When heated to decomposition it emits very toxic fumes of Na2O and SOx. See also SODIUM THIOSULFATE and SODIUM THIOSULFATE, PENTAHYDRATE.
  • Veterinary Drugs and Treatments Sodium thiosulfate (alone or in combination with sodium nitrite) is useful in the treatment of cyanide toxicity. It has been touted for use in treating arsenic or other heavy metal poisonings, but its efficacy is in question for these purposes. However, because sodium thiosulfate is relatively non-toxic and inexpensive, it may be tried to treat arsenic poisoning. When used in combination with sodium molybdate, sodium thiosulfate may be useful for the treatment of copper poisoning.
    Sodium thiosulfate may be useful for the topical treatment for some fungal infections (Tinea). In humans, sodium thiosulfate has been used to reduce the nephrotoxicity of cisplatin therapy. A 3 or 4% solution has been used to infiltrate the site of extravasations of cisplatin, carboplatin, or dactinomycin. In combination with steroids, sodium thiosulfate may reduce the healing time associated with doxorubicin extravasation.
  • läuterung methode Crystallise it from EtOH/H2O solutions or from water (0.3mL/g) below 60o by cooling to 0o, and dry it at 35o over P2O5 under vacuum. [Foerster & Mommsen Chem Ber 57 258 1924.] This salt is used as a secondary standard in volumetric analysis [Kilpatrick J Am Chem Soc 45 2132 1923], and is used as “Hypo” in photography [Hargreaves & Dunningham J Soc Chem Ind 42 147T 1923.]
