Its chemical formula is sometimes written in a semistructural format, as ()2−. The sulfur atoms of the dithionate ion are in the +5 oxidation state due to the presence of the S-S bond. Generally dithionates form stable compounds that are not readily oxidised or reduced. Strong oxidants oxidise them to sulfates and strong reducing agents reduce them to sulfites and dithionites. Aqueous solutions of dithionates are quite stable and can be boiled without decomposition.〔 〕 The γ irradiation of crystalline dithionates produces SO3− radical ions.〔''Radiation Chemistry of Dithionates'' G.S. Murthy, R.L. Eager, and K.J. McCallum Can. J. Chem. 49(22),(1971), 3733〕 The unpaired electron in the SO3− radical can be detected with electron paramagnetic resonance and barium dithionate has been proposed as the basis for a radiation dosimeter.〔''Barium dithionate as an EPR dosemeter'' Baran M.P., Bugay O.A., Kolesnik S. P., Maksimenko V. M., Teslenko V. V., Petrenko T. L. Desrosiers M. F. Radiation Protection Dosimetry 2006 120, 202; 〕 The dithionate ion can act as a bidentate ligand.〔''Structures of Some Copper (II) Complexes Containing S2O62− Ion'' Ishii M. Bulletin of the Yamagata University 5, 1,(2001), 7 〕 The structure of the dithionate ion in the solid state is staggered in Na2S2O6.2H2O, whereas in the anyhydrous potassium salt it is nearly eclipsed.〔 ==Compounds== Compounds containing the dithionate ion include: * sodium dithionate, Na2S2O6 * potassium dithionate, K2S2O6 * barium dithionate, BaS2O6 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dithionate」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
