Product Description:
Sodium thiosulfate solution is widely used in medical treatments as an antidote for cyanide poisoning. It works by converting cyanide into a less toxic substance, thiocyanate, which is then excreted by the body.
In photography, it serves as a fixing agent to dissolve unexposed silver halides from photographic films and papers, ensuring the image remains stable and clear.
It is also employed in water treatment to neutralize chlorine in dechlorination processes, making water safer for discharge into the environment or for use in aquariums.
Additionally, it finds application in analytical chemistry as a titrant in iodometric titrations to determine the concentration of oxidizing agents.
In the textile industry, it is used to remove excess chlorine after bleaching fabrics, preventing damage and ensuring colorfastness.
Lastly, it plays a role in gold extraction, where it helps dissolve gold from ores in an environmentally friendly alternative to cyanide-based methods.
