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.

Sodium metasilicate is the chemical substance with formula Na 2 SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na +
For simplicity, the equations will usually be written in terms of aqueous molecular iodine rather than the triiodide ion, as the iodide ion did not participate in the reaction in terms of mole ratio analysis. The disappearance of the deep blue color is, due to the decomposition of the iodine-starch clathrate, marks the end point.
In chromogenic films, the remaining silver must be removed by a chemical mixture called a bleach fix, sometimes shortened to blix. This mixture contains ammonium thiosulfate and ferric EDTA, a powerful chelating agent. The fixing agent reduces the silver which is then dissolved by the chelating agent.
Sodium oxide is a chemical compound with the formula Na 2 O.It is used in ceramics and glasses.It is a white solid but the compound is rarely encountered. Instead "sodium oxide" is used to describe components of various materials such as glasses and fertilizers which contain oxides that include sodium and other elements.
Sodium thiosulfate is a classical antidote to cyanide poisoning, [10] For this purpose it is used after the medication sodium nitrite and typically only recommended for severe cases.
