sodium thiosulfate boiling point
The boiling point of a substance is the temperature at which it becomes liquid. It is a measurement of the energy required to melt or boil the substance, and is used in various industrial processes.
Sodium thiosulfate pentahydrate (Na2S2O3) is a chemical compound that is primarily produced from the synthesis of sulphur dyes in the laboratory. This compound is also prepared industrially by heating aqueous solutions of sodium sulfate and sulphur.
This substance has a variety of industrial applications such as in the production of chemicals, textile, leather or fur, pulp, paper and paper products, metals, fabricated metal products, electrical, electronic and optical equipment and machinery and vehicles. It is widely used as a food preservative and has also been employed as a pharmaceutical agent.
It is a sequestrant, antioxidant and formulation aid. It is often added to alcoholic beverages and table salt at low levels, as a preservative for a variety of foods, and in the preparation of medicines, including iodine-containing tablets.
Sodium thiosulfate is also an important analytical reagent, and is utilized in iodometric titration to analyze chlorine, bromine and sulfide. It is also used as a bleach to remove sulfide from paper, straw, ivory and bone; as a mordant in dyeing and printing textiles; as a fixer for silver halides in photography; and as an antidote for cyanide poisoning.
Sodium thiosulfate has a wide range of important medical applications as well, such as treating pityriasis versicolor and side effects of the cancer drug cisplatin. It is frequently given as a treatment for cyanide poisoning, after the drug sodium nitrite is administered.
