MERCUROUS NITRATE Chemical Properties,Usage,Production

Chemical Properties

Mercurous nitrate,HgN03•2H20, is colorless,efflorescent, light-sensitive crystals that decompose in water,and melt at 70℃. Also known as hydrated mercurous nitrate, it is highly toxic and explosive if shocked or heated and is used as an analytical agent.

Purification Methods

Its solubility in H2O containing 1% HNO3 is 7.7%. Recrystallise it from a warm saturated solution of dilute HNO3 and cool to room temperature slowly to give elongated prisms. Rapid cooling gives plates. The colourless crystals should be stored in the dark. POISONOUS. [Grdenic J Chem Soc 1312 1956.]
