What is Sodium thiosulfate (7772-98-7) used for?
Sodium Thiosulfate, also known as sodium hyposulfite or sodium soda, manifests as colorless and transparent monoclinic crystals. It exhibits solubility in water and is nearly neutral in aqueous solution. Insoluble in ethanol and deliquescent in humid air, sodium thiosulfate is prone to weathering in air temperatures exceeding 33°C. Additionally, it possesses reducing properties, dissolves silver halide, and undergoes decomposition into sodium sulfide and sodium sulfate when heated.
