|Section2= |Section3= |Section7= |Section8= }} Mercury(I) nitrate is a chemical compound with the formula Hg2(NO3)2. It is used in the preparation of other mercury(I) compounds, and, like all other mercury compounds, it is toxic. ==Reactions== Mercury(I) nitrate is formed when elemental mercury is combined with ''dilute'' nitric acid (concentrated nitric acid will yield mercury(II) nitrate). Mercury(I) nitrate is a reducing agent which is oxidized upon contact with air. Solutions of mercury(I) nitrate are acidic due to slow reaction with water: :Hg2(NO3)2 + H2O → Hg2(NO3)(OH) + HNO3 Hg2(NO3)(OH) forms a yellow precipitate. If the solution is boiled or exposed to light, mercury(I) nitrate undergoes a disproportionation reaction yielding elemental mercury and mercury(II) nitrate:〔 :Hg2(NO3)2 → Hg + Hg(NO3)2 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「Mercury(I) nitrate」の詳細全文を読む スポンサード リンク
