Applications

Sodium thiosulfate solution (2 g/dL in deionized water) is widely utilized in research focused on:

  • Medical Applications: It is commonly used in the treatment of cyanide poisoning, acting as an antidote by converting toxic cyanide into a less harmful compound, thiocyanate, which can be excreted by the body.
  • Photography: This solution serves as a fixing agent in photographic processes, helping to stabilize images by removing unreacted silver halides, thus preventing further exposure to light.
  • Water Treatment: Sodium thiosulfate is effective in dechlorinating water, making it suitable for aquaculture and swimming pools by neutralizing chlorine and chloramine, ensuring a safe environment for aquatic life and swimmers.
  • Analytical Chemistry: It is used in titrations to determine the concentration of oxidizing agents, providing a reliable method for quantitative analysis in laboratories.
  • Industrial Applications: In the textile industry, it aids in the dyeing process by helping to remove excess dye and improve color fastness, enhancing the quality of dyed fabrics.
