Sodium Thiosulphate

Photography: Sodium Thiosulfate is a key component in photographic processing, where it is used as a fixing agent to remove unexposed and undeveloped silver halide crystals from photographic film and paper. This step is essential for making photographs permanent and preventing further exposure to light.

Medical Uses: It is used in some medical applications to reduce the irritation and pain associated with skin and mucous membrane conditions. Sodium Thiosulfate can be used as an antidote for cyanide poisoning, as it forms a complex with cyanide ions and helps detoxify them.

Water Treatment: Sodium Thiosulfate may be used in water treatment processes to neutralize residual chlorine in water, which is important for dechlorination.

Analytical Chemistry: It is employed as a reagent in various chemical analysis and laboratory experiments. Sodium Thiosulfate can be used in titration reactions, particularly for determining the concentration of iodine or other oxidizing agents.

Gold and Silver Recovery: It is used in mining and metallurgical processes to recover gold and silver from their ores by forming soluble complexes.

Industrial Applications: Sodium Thiosulfate is used in certain industrial processes, such as in the textile industry to remove excess chlorine from fabrics.

Food Dechlorination: In the food industry, it can be used to remove chlorine and chloramine from tap water used in food processing.
