This bright red salt contains the octahedrally coordinated [Fe(CN)6] ion. It is soluble in water and its solution shows some green-yellow fluorescence. It was discovered in 1822 by Leopold Gmelin. Skatīt vairāk Potassium ferricyanide is manufactured by passing chlorine through a solution of potassium ferrocyanide. Potassium ferricyanide separates from the solution: 2 K4[Fe(CN)6] + Cl2 → 2 K3[Fe(CN)6] + 2 KCl Skatīt vairāk Like other metal cyanides, solid potassium ferricyanide has a complicated polymeric structure. The polymer consists of octahedral [Fe(CN)6] centers crosslinked with K ions that are bound to the CN ligands. The K ---NCFe linkages break when the solid is … Skatīt vairāk Prussian blue, the deep blue pigment in blue printing, is generated by the reaction of K3[Fe(CN)6] with ferrous (Fe ) ions as well as K4[Fe(CN)6] with ferric salts. In histology, potassium ferricyanide is used to detect ferrous iron in biological tissue. Potassium … Skatīt vairāk • International Chemical Safety Card 1132 • National Pollutant Inventory – Cyanide compounds fact sheet Skatīt vairāk The compound is also used to harden iron and steel, in electroplating, dyeing wool, as a laboratory reagent, and as a mild oxidizing agent in organic chemistry.
