|Section2= |Section3= |Section7= |Section8= }} Ammonium persulfate (APS) is the inorganic compound with the formula (NH4)2S2O8. It is a colourless (white) salt that is highly soluble in water, much more so than the related potassium salt. It is a strong oxidizing agent that is used in polymer chemistry, as an etchant, and as a cleaning and bleaching agent. The dissolution of the salt in water is an endothermic process. ==Preparation== Ammonium persulfate is prepared by electrolysis of a cold concentrated solution ammonium sulfate in sulfuric acid at a high current density.〔F. Feher, "Potassium Peroxydisulfate" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 390.〕 The method was first described by H. Marshall. 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「ammonium persulfate」の詳細全文を読む スポンサード リンク
