Chemical compound

Mercury(II) nitrate is an inorganic compound with the chemical formula Hg(NO₃)₂. It is the mercury(II) saltofnitric 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.^[1] The anhydrous material is more widely used.^{[clarification needed]}

Uses[edit]

Mercury(II) nitrate has been used in mercurationofketones.^[2] Mercury(II) nitrate was formerly used in carroting felt for hats.

Health information[edit]

Mercury compounds are highly toxic. The use of this compound by hatters and the subsequent mercury poisoning of said hatters is a common theory of where the phrase "mad as a hatter" came from.
