sodium thiosulfate pentahydrate, also known as soda, hyperion. For monoclinic white crystalline powder, soluble in water, insoluble in alcohol.
It is widely used in analytical reagents and so on.
Chemical formula: Na2S2O3, specific gravity 1.667,
Heated in air, it is oxidized to sodium sulfate and sulfur dioxide. With a specific gravity of 1.667, the heat is easily decomposed and broken down into sodium sulfate and sulfur or sodium sulfate and sodium polysulfide, simultaneously oxidized by oxygen. The sodium thiosulfate breaks down with acid and emits sulfur dioxide gas and produces sulfur deposits. Heated in air and oxidized to sodium sulfate and sulfur dioxide. When the air combustion is generated under sodium sulfate, sodium sulfide and sulfur. It should be stored in a cool and dry warehouse. It should not be mixed with acids or oxidants.

Sodium thiosulfate pentahydrate chemical property

Reduction: large soda also has a strong reduction, chlorine and other substances can be reduced
Na2S2O3+4Cl2+5H2O=2H2SO4+2NaCl+6HCl, so it can dechlorine agent as cotton fabric bleaching. Similarly, iodine stains on the fabric can also be used to remove it. In addition, soda is also used in leather tanning, electroplating and silver in Ores by extraction.
Complex: soda has a strong complexing ability, can form a complex with silver bromide. Reaction formula: AgBr+2Na2S2O3=NaBr+Na3[Ag (S2O3) 2], according to this character, it can be used as fixing agent. Washing phase, the excessive amount of soda with the film is not part of the photosensitive silver bromide reaction, into soluble Na3[Ag (S2O3) 2], the AgBr get rid of, so that the developing of some fixed

Use:
Used as a fixer in photographic industry. Electroplating, purifying water and used for tanning leather, reducing agent, bleaching of cotton fabrics is also used for chemical industry after dechlorination agent, wool fabrics dyed with sulfur dye, indigo dye agent, anti white pulp dechlorination agent, pharmaceutical industry used in detergents and disinfectants and bleaching agent.
