Two sodium cations coordinate with every one anion.〔Braithwaite, E.R.; Haber, J. ''Molybdenum: An outline of its Chemistry and Uses.'' 1994. Elsevier Science B.V. Amsterdam, The Netherlands.〕 ==History== Sodium molybdate was first synthesized by the method of hydration.〔Spitsyn, Vikt. I.; Kuleshov, I. M. ''Zhurnal Obshchei Khimii'' 1951. 21. 1701-15.〕 A more convenient synthesis is done by dissolving MoO3 in sodium hydroxide at 50–70 °C and crystallizing the filtered product.〔 The anhydrous salt is prepared by heating to 100 °C. :MoO3 + 2NaOH + H2O → Na2MoO4·2H2O 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 molybdate」の詳細全文を読む スポンサード リンク
