mercurous nitrate dihydrate, Hg2(NO3)2, is a white insoluble salt that is the mercury (I) nitrate salt with the formula HgNNO3. It is found as a free element and also as a mineral — it occurs in cinnabar, corderoite, and livingstonite ores. Like all mercury compounds, it is toxic. It is noncombustible and, in addition, it oxidizes rapidly to give off toxic mercury vapor and oxides of nitrogen. It is slightly soluble in water but decomposes to form an insoluble precipitate. It meets ACS Reagent Grade specifications.
