Call us toll free at: 855-248-9059 Description: Sodium thiosulfate (Na2S2O3), also spelled sodium thiosulphate, is a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3·5H2O, anefflorescent, monoclinic crystalline substance also called sodium hyposulfite or “hypo”. Uses: In photography (fixing agent to dissolve unchanged silver salts from exposed negatives), chrome tanning, removing chlorine in bleaching and paper making. Gold extraction: Sodium thiosulfate is a component of an alternative lixiviant to cyanide for extraction of gold. However, it forms a strong soluble complex with gold(I) ions, [Au(S2O3)2]3–. The advantage of this approach is that thiosulfate is essentially not toxic and that ore types that are refractory to gold cyanidation (e.g. carbonaceous or Carlin-type ores) can be leached by thiosulfate. 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. Aluminium cation reaction: Sodium thiosulfate is also used in analytical chemistry.[citation needed] It can, when heated with a sample containing aluminium cations, produce a white precipitate: 2 Al3+ + 3 S2O32– + 3 H2O -> 3 SO2 + 3 S + 2 Al(OH)3 Our Chemical Products are shipped with current globally harmonized Safety Data Sheets and Labeling. Quantities smaller than original package are carefully repackaged and sealed in smaller Foil, Plastic, or HDPE containers.

Grade Definitions applied by manufacturer to original package are as follows: U.S.P. / Food Grade: A chemical grade of sufficient purity to meet or exceed requirements of the United States Pharmacopeia (USP); acceptable for food, drug, or medicinal use; may be used for most laboratory purposes. A.C.S.: A chemical grade of highest purity and meets or exceeds purity standards set by American Chemical Society (ACS). Reagent: High purity generally equal to A.C.S. grade and suitable for use in many laboratory and analytical applications. Technical: Good quality chemical grade used for commercial and industrial purposes. Not pure enough to be offered for food, drug, or medicinal use. N.F.: A grade of sufficient purity to meet or exceed requirements of the United States National Formulary. (Since bought out and merged with the United States Pharmacopeia, USP-NF.) Lab: A chemical grade of relatively high quality with exact levels of impurities unknown; usually pure enough for educational applications. Not pure enough to be offered for food, drug, or medicinal use. Purified: Also called pure or practical grade, and indicates good quality chemicals meeting no official standard; can be used in most cases for educational applications. Not pure enough to be offered for food, drug, or medicinal use. PURCHASE REQUIREMENTS / Terms of sale. To purchase products you must meet the following criteria.
