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 ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
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.
Water for injection is generally made by distillation or reverse osmosis. [5] It should contain less than a mg of elements other than water per 100 ml. [5] Versions with agents that stop bacterial growth are also available. [5] In the UK, some hospitals offer subcutaneous injections of water directly for treating back pain in labour.
Prussian white, also known as Berlin white or Everett's salt, is the sodium end-member of the totally reduced form of the Prussian blue in which all iron is present as Fe(II). It is a sodium hexacyanoferrate of Fe(II) of formula Na 2 Fe[Fe(CN) 6]. [29] Its molecular weight value is 314 g/mol. [29]
Ammonium hexacyanoferrate(II) is an inorganic chemical compound with the chemical formula ... The compound is well-soluble in water, and does not dissolve in ethanol.
In the EU, hexacyanidoferrates(II) (E 535–538) were, as of 2017, solely authorised in two food categories as salt additives. It can also be used in animal feed. [9] In the laboratory, potassium hexacyanidoferrate(II) is used to determine the concentration of potassium permanganate, a compound often used in titrations based on redox reactions.
Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive caesium poisoning. [ 1 ] [ 2 ] For thallium it may be used in addition to gastric lavage , activated charcoal , forced diuresis , and hemodialysis .
