CAS 7772-98-7
:Sodium thiosulfate
Description:
Sodium thiosulfate, with the CAS number 7772-98-7, is an inorganic compound commonly represented by the formula Na2S2O3. It appears as a white, crystalline solid that is highly soluble in water, forming a colorless solution. Sodium thiosulfate is known for its reducing properties and is often used in various applications, including photography, water treatment, and as an antidote for cyanide poisoning. It acts by converting toxic cyanide into a less harmful compound. The substance is also utilized in analytical chemistry as a titrant in redox reactions, particularly in iodometric titrations. In addition to its chemical reactivity, sodium thiosulfate is relatively stable under normal conditions but can decompose when exposed to strong acids or heat, releasing sulfur dioxide and other products. Its safety profile indicates that it is generally considered non-toxic, although it can cause irritation to the skin and eyes upon contact. Overall, sodium thiosulfate is a versatile compound with significant utility in both industrial and laboratory settings.
