  2. Sodium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Sodium_ferrocyanide

    Sodium ferrocyanide is produced industrially from hydrogen cyanide, ferrous chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O.A solution of this salt is then treated with sodium salts to precipitate the mixed calcium-sodium salt CaNa 2 [Fe(CN) 6] 2, which in turn is treated with sodium carbonate to give the tetrasodium salt.

  3. Ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Ferrocyanide

    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.

  4. List of elements by atomic properties - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by_atomic...

    This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.

  6. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).

  7. Iron compounds - Wikipedia

    en.wikipedia.org/wiki/Iron_compounds

    An example of a low-spin iron(III) complex is [Fe(CN) 6] 3−. The cyanide ligands may easily be detached in [Fe(CN) 6 ] 3− , and hence this complex is poisonous, unlike the iron(II) complex [Fe(CN) 6 ] 4− found in Prussian blue, [ 16 ] which does not release hydrogen cyanide except when dilute acids are added. [ 17 ]

  8. Hydrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_compounds

    Water molecules have two hydrogen atoms and one oxygen atom. While H 2 is not very reactive under standard conditions, it does form compounds with most elements. Hydrogen can form compounds with elements that are more electronegative, such as halogens (F, Cl, Br, I), or oxygen; in these compounds hydrogen takes on a partial positive charge. [1]

  9. Potassium ferrocyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ferrocyanide

    Potassium hexacyanidoferrate(II) is produced industrially from hydrogen cyanide, iron(II) chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O. This solution is then treated with potassium salts to precipitate the mixed calcium-potassium salt CaK 2 [Fe(CN) 6 ], which in turn is treated with potassium ...
