Sodium ferrocyanide is the sodium salt of the coordination compound of formula [Fe(CN) 6] 4−. In its hydrous form, Na 4 Fe(CN) 6 · H 2 O (sodium ferrocyanide decahydrate), it is sometimes known as yellow prussiate of soda. It is a yellow crystalline solid that is soluble in water and insoluble in alcohol. The yellow color is the color of ...
Ferrocyanide is the name of the anion [Fe 6] 4−. Salts of this coordination complex give yellow solutions. It is usually available as the salt potassium ferrocyanide, which has the formula K 4 Fe(CN) 6. [Fe(CN) 6] 4− is a diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment.
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
Like other metal cyanides, solid potassium hexacyanidoferrate(II), both as the hydrate and anhydrous salts, has a complicated polymeric structure. The polymer consists of octahedral [Fe(CN) 6] 4− centers crosslinked with K + ions that are bound to the CN ligands. [10] The K +---NC linkages break when the solid is dissolved in water.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N. It is an azide compound of carbon and nitrogen. It is an oily, colourless liquid at room temperature. [2] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.
The main aqueous species are the aquo complexes [Na(H 2 O) n] +, where n = 4–8; with n = 6 indicated from X-ray diffraction data and computer simulations. [13] Direct precipitation of sodium salts from aqueous solutions is rare because sodium salts typically have a high affinity for water. An exception is sodium bismuthate (NaBiO 3). [14]
Prussian blue or "ferric ferrocyanide", Fe 4 [Fe(CN) 6] 3, is an old and well-known iron-cyanide complex, extensively used as pigment and in several other applications. Its formation can be used as a simple wet chemistry test to distinguish between aqueous solutions of Fe 2+ and Fe 3+ as they react (respectively) with potassium ferricyanide and ...
The [Fe(EDTA)(H 2 O)] − anion has been crystallized with many cations, e.g., the trihydrate Na[Fe(EDTA)(H 2 O)]. 2H 2 O. [3] The salts as well as the solutions are yellow-brown. Provided the nutrient solution in which the [Fe(EDTA)(H 2 O)] − complex will be used has a pH of at least 5.5, all the uncomplexed iron, as a result of incomplete ...
