Product Description:
Sodium thiosulfate pentahydrate is widely used in photography as a fixing agent to dissolve unexposed silver halides from photographic emulsions, ensuring the image remains stable and clear. In medical applications, it serves as an antidote for cyanide poisoning by converting cyanide into thiocyanate, which is less toxic and can be excreted by the body. It is also employed in water treatment to neutralize chlorine and chloramine, making water safer for discharge or reuse. Additionally, it is used in analytical chemistry as a titrant in iodometric titrations to determine the concentration of oxidizing agents. In the textile industry, it helps in the process of bleaching and dechlorination of fabrics. Its ability to act as a reducing agent makes it valuable in various industrial processes, including gold extraction and leather tanning.
