Sodium tetrathionate is a salt of sodium and tetrathionate with the formula Na2S4O6.xH2O. The salt normally is obtained as the dihydrate (x = 2). It is a colorless, water-soluble solid. It is a member of the polythionates, which have the general formula [Sn(SO3)2]2-. Other members include trithionite (n = 1), pentathionate (n = 3), hexathionate (n = 4). Sodium tetrathionate is formed by the oxidation of sodium thiosulfate (Na2S2O3), e.g. by the action of iodine: 2 Na2S2O3 + I2 → Na2S4O6 + 2 NaI Other methods include the coupling of sodium bisulfite with disulfur dichloride:

dbo:abstract
  • رباعي الثيونات هو أنيون أكسجيني للكبريت صيغته 2-S4O6، وهو ملح حمض رباعي الثيونيك، وهو أحد أحماض متعددة الثيونيك. (ar)
  • Natria kvartionato, kvartionato de natrio aŭ Na2S4O6 estas neorganika okso-kombinaĵo de natrio kaj sulfuro, iom simila al molekuloj de natria tiosulfato kunligitaj per du sulfuratomoj. Natria kvartionato formiĝas per oksidado de natria tiosulfato kaj likva jodo, kies salo rezultanta povas izoliĝi el la solvaĵo per frakcia kristaliĝo. (eo)
  • Sodium tetrathionate is a salt of sodium and tetrathionate with the formula Na2S4O6.xH2O. The salt normally is obtained as the dihydrate (x = 2). It is a colorless, water-soluble solid.

Sodium tetrathionate is formed by the oxidation of sodium thiosulfate (Na2S2O3), e.g. by the action of iodine: 2 Na2S2O3 + I2 → Na2S4O6 + 2 NaI The reaction is signaled by the decoloration of iodine. This reaction is the basis of iodometric titrations. Other methods include the coupling of sodium bisulfite with disulfur dichloride: 2 NaHSO3 + S2Cl2 → Na2S4O6 + 2 HCl The ion has ideal C2 symmetry, like H2S2. The S-S-S dihedral angle is nearly 90°. The central S-S distance is 2.115 Å, 0.01 Å longer than the two other S-S distances as well as those distances in most polysulfanes. (en)
