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.
It is prepared by treating Grignard reagents derived from XC 6 H 3-3,5-(CF 3) 2 (X = Br, I) with NaBF 4. A popular method is summarized in the following equation: [6] NaBF 4 + 4 Ar F MgBr → 4 MgBrF + NaBAr F 4. Brookhart's acid is the salt of the BARF anion with the diethyl ether oxonium cation, [(Et 2 O) 2 H]BAr F 4.
The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...
Ascorbic acid works both as an acidulant and as a reducing agent, converting nitrite into nitrous acid and then reducing it to nitrogen monoxide, which will then bind to iron ions forming nitrosyl complexes, which will react with sulfide in a basic medium giving Roussin's red salt. [8] 2FeSO 4 + 4HNO 2 + 3C 6 H 8 O 6 + 2Na 2 S + 2NaOH → Na 2 ...
The anion [Ce(NO 3) 6] 2− is generated by dissolving Ce 2 O 3 in hot and concentrated nitric acid (HNO 3). [2] The salt consists of the hexanitratocerate(IV) anion [Ce(NO 3) 6] 2− and a pair of ammonium cations NH + 4. The ammonium ions are not involved in the oxidising reactions of this salt.
Aliquat 336 is used as a phase transfer catalyst, [2] including in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. [3] This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
