|Section2= |Section3= }} Sodium stannate is the inorganic compound with the formula Na2Sn(OH)6. This colourless salt forms upon dissolving tin or tin dioxide in sodium hydroxide. Sodium stannate is used as a stabiliser for hydrogen peroxide.〔Clark, John D. (1972). Ignition! An Informal History of Liquid Rocket Propellants. New Brunswick, New Jersey: Rutgers University Press. ISBN 0-8135-0725-1.〕 Alkali metal stannate compounds are prepared by dissolving tin in sodium hydroxide:〔Greenwood, N. N.; & Earnshaw, A. (1997). Chemistry of the Elements (2nd Edn.), Oxford:Butterworth-Heinemann. ISBN 0-7506-3365-4.〕 :Sn + 2 NaOH + 4 H2O → Na2() + 2 H2 A similar reaction occurs when tin dioxide is dissolved in base: :SnO2 + 2 NaOH + 2 H2O → Na2() The anion is octahedral as are most stannates, e.g., the hexachlorostannate anion ()2−. The Sn-O distances average 2.071 Å.〔Herbert Jacobs Rainer Stahl "Neubestimmung der Kristallstrukturen der Hexahydroxometallate Na2Sn(OH)6, K2Sn(OH)6 und K2Pb(OH)6" Zeitschrift für anorganische und allgemeine Chemie 2000, Volume 626, pages 1863–1866. 〕 In some old literature, stannates are sometimes represented as the simple oxyanion SnO32−. ==References== 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「Sodium stannate」の詳細全文を読む スポンサード リンク
