Chemical Properties
Safety Information
Product Usage
Sodium Thiosulfate, commonly known as Hypo, is a versatile inorganic salt with diverse functional applications. In the photography industry, it serves as a classic fixing agent to dissolve unexposed silver halides from films. In water treatment, it is a highly effective dechlorinating agent, widely used to neutralize residual chlorine in tap water or industrial effluent to protect aquatic life. In the medical field, it acts as an indispensable antidote for cyanide poisoning and is used to mitigate the side effects of certain chemotherapy drugs. Furthermore, it is extensively applied in the textile and paper industries for bleaching dechlorination, in leather tanning, and in hydrometallurgy for extracting gold and silver from ores.
