Mercury(II) nitrate is an inorganic compound with the chemical formula Hg(N O₃)₂. It is the mercury(II) salt of nitric acid HNO₃. It contains mercury(II) cations Hg²⁺ and nitrate anions NO−3, and water of crystallization H₂O in the case of a hydrous salt. Mercury(II) nitrate forms hydrates Hg(NO₃)₂·xH₂O. Anhydrous and hydrous salts are colorless or white soluble crystalline solids that are occasionally used as a reagents. Mercury(II) nitrate is made by treating mercury with hot concentrated nitric acid. Neither anhydrous nor monohydrate has been confirmed by X-ray crystallography. The anhydrous material is more widely used.
