|Section2= |Section3= |Section7= |Section8= }} Cobalt(II) bromide (CoBr2) is an inorganic compound. It is a red solid that is soluble in water, used primarily as a catalyst in some processes. ==Properties== When anhydrous, cobalt(II) bromide appears as green crystals. The hexahydrate loses four waters of crystallization molecules at 100 °C forming the dihydrate: :CoBr2.6H2O → CoBr2.2H2O + 4 H2O Further heating to 130 °C produces the anhydrous form: :CoBr2.2H2O → CoBr2 + 2 H2O The anhydrous form melts at 678 °C.〔(Cobalt Bromide Supplier & Tech Info ) American Elements〕〔(WebElements Periodic Table of the Elements )〕 At higher temperatures, cobalt(II) bromide reacts with oxygen, forming cobalt(II,III) oxide and bromine vapor. 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「Cobalt(II) bromide」の詳細全文を読む スポンサード リンク
