Sodium thiosulfate solution is widely used in various fields due to its versatile properties. In photography, it serves as a fixing agent to remove unexposed silver halides from photographic films and papers, ensuring the image remains stable. In medical applications, it is employed as an antidote for cyanide poisoning, where it helps convert cyanide into a less toxic compound, thiocyanate, which can be excreted by the body. Additionally, it is used in water treatment to neutralize chlorine and chloramine, making water safer for discharge into the environment or for use in aquariums. In analytical chemistry, it acts as a titrant in iodometric titrations to determine the concentration of oxidizing agents. It also finds use in the textile industry for dechlorination after bleaching processes, ensuring fabric quality and safety.
