Alkylation of sodium thiosulfate gives S-alkylthiosulfates, which are called Bunte salts. [16] The alkylthiosulfates are susceptible to hydrolysis, affording the thiol. This reaction is illustrated by one synthesis of thioglycolic acid: ClCH 2 CO 2 H + Na 2 S 2 O 3 → Na[O 3 S 2 CH 2 CO 2 H] + NaCl Na[O 3 S 2 CH 2 CO 2 H] + H 2 O → HSCH 2 CO ...
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.

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.
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.
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
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 persulfate is a specialized oxidizing agent in chemistry, classically in the Elbs persulfate oxidation and the Boyland–Sims oxidation reactions. It is also used in radical reactions; for example in a synthesis of diapocynin from apocynin where iron(II) sulfate is the radical initiator. [7]
