Sodium thiosulfate is used in the treatment of cyanide poisoning. [3] It is on the World Health Organization's List of Essential Medicines. [4] [5] Other uses include topical treatment of ringworm and tinea versicolor, [3] [6] and treating some side effects of hemodialysis [7] and chemotherapy.
Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S 2 O 2− 3.Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid, such as sodium thiosulfate Na 2 S 2 O 3 and ammonium thiosulfate (NH 4) 2 S 2 O 3.
In September 2022, the U.S. Food and Drug Administration (FDA) approved sodium thiosulfate under the brand name Pedmark to lessen the risk of ototoxicity and hearing loss in infant, child, and adolescent cancer patients receiving the chemotherapy medication cisplatin.
By this definition, the number of equivalents of a given ion in a solution is equal to the number of moles of that ion multiplied by its valence. For example, consider a solution of 1 mole of NaCl and 1 mole of CaCl 2. The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −.
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3.A white, water-soluble solid, it is used commercially as an antioxidant and preservative.

Sodium dithionate is produced by the oxidation of sodium bisulfite by manganese dioxide: [1]. 2 NaHSO 3 + MnO 2 → Na 2 S 2 O 6 + MnO + H 2 O. Alternatively, it can be prepared by the oxidation of sodium sulfite by the silver(I) cation: [1]
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
