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:[2]
- Hg2(NO3)2 → Hg + Hg(NO3)2
