Chemical formula: Na 2 [Fe(CN) 5 NO]・2H 2 O. Official name is sodium pentacyanonitrosylferrate(III). It is obtained by neutralizing the solution obtained by reacting potassium ferrocyanide with nitric acid with sodium carbonate. Ruby-colored orthorhombic crystals. Specific gravity: 1.71. Dissolves 400 g in 1 liter of water at 16°C. Easily soluble in alcohol. Stable as a crystal but unstable in solution. In an alkaline environment, it reacts with alkali metal sulfides to produce the red-purple complex Na 4 [Fe(CN) 5 NOS]. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
化学式Na2[Fe(CN)5NO]・2H2O。正式名はペンタシアノニトロシル鉄(III)酸ナトリウム。フェロシアン化カリウムと硝酸との反応によって得た液を炭酸ナトリウムで中和して得られる。ルビー色の斜方晶系結晶。比重1.71。16℃で水1lに400g溶ける。アルコールにも易溶。結晶としては安定であるが溶液中では不安定である。アルカリ性でアルカリ金属硫化物と反応して赤紫色錯体Na4[Fe(CN)5NOS]を生じる。
