|Section2= |Section7= }} Mercury(II) thiocyanate (Hg(SCN)2) is an inorganic chemical compound, the coordination complex of Hg2+ and the thiocyanate anion. It is a white powder. It will produce a large, winding “snake” when ignited, an effect known as the Pharaoh’s Serpent. ==Synthesis== The first synthesis of mercury thiocyanate was probably completed in 1821 by Jöns Jacob Berzelius: :HgO + 2 HSCN → Hg(SCN)2 + H2O Evidence for the first pure sample was presented in 1866 prepared by a chemist named Otto Hermes.〔 It is prepared by treating solutions containing mercury(II) and thiocyanate ions. The low solubility product of mercury thiocyanate causes it to precipitate from solution. Most syntheses are achieved by precipitation: :Hg(NO3)2 + 2 KSCN → Hg(SCN)2 + 2KNO3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mercury(II) thiocyanate」の詳細全文を読む スポンサード リンク
