It is a component of silver oxide-zinc alkaline batteries. It can be prepared by the slow addition of a silver(I) salt to a persulfate solution e.g. AgNO3 to a Na2S2O8 solution.〔 It adopts an unusual structure, being a mixed-valence compound.〔David Tudela "Silver(II) Oxide or Silver(I,III) Oxide?" J. Chem. Educ., 2008, volume 85, p 863. 〕 It is a dark brown solid that decomposes with evolution of O2 in water. It dissolves in concentrated nitric acid to give brown solutions containing the Ag2+ ion.〔 Peter Fischer, Martin Jansen "Electrochemical Syntheses of Binary Silver Oxides" 1995, vol. 30, pp. 50–55. 〕 ==Structure== Although its empirical formula, AgO, suggests that silver is in the +2 oxidation state in this compound, AgO is in fact diamagnetic. X-ray diffraction studies show that the silver atoms adopt two different coordination environments, one having two collinear oxide neighbours and the other four coplanar oxide neighbours.〔Wells A.F. (1984) ''Structural Inorganic Chemistry'' 5th edition Oxford Science Publications ISBN 0-19-855370-6〕 AgO is therefore formulated as AgIAgIIIO2〔 p. 1181.〕 or Ag2O·Ag2O3. It is being a 1:1 molar mixture of silver(I) oxide, Ag2O, and silver(III) oxide, Ag2O3. It has previously been called silver peroxide, which is incorrect since does not contain the peroxide ion, O22−. 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「Silver(I,III) oxide」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.
