Product description

Sodium thiosulfate pentahydrate, with a purity of 99%, is a chemical compound with the molecular formula Na2S2O3·5H2O. It is a white crystalline solid that is highly soluble in water.
  • Function: Sodium thiosulfate pentahydrate has various applications, including as a photographic fixer, an antidote for cyanide poisoning, a water dechlorinator, and a neutralizer for iodine solutions. In photography, it is used to remove unexposed silver halide from photographic film and paper after development, fixing the image onto the medium.
  • Application: Sodium thiosulfate pentahydrate is commonly used in the photographic industry as a fixer to stabilize developed images. It is also utilized in water treatment to neutralize excess chlorine in swimming pools and tap water. Additionally, it serves as an important reagent in analytical chemistry and medical applications.
  • Characteristics: Sodium thiosulfate pentahydrate is a stable compound with a relatively high solubility in water. It is non-toxic and non-flammable, making it safe to handle and store. The pentahydrate form contains five water molecules in its crystal structure, which can affect its handling properties and solubility.
  • Usage: Sodium thiosulfate pentahydrate is typically added to photographic fixer solutions or water treatment systems in the appropriate concentration to achieve the desired effect. In photography, it is used as part of the developing and fixing process, while in water treatment, it is used to neutralize chlorine residuals.
