El ferricianuro potásico se fabrica pasando cloro a través de una solución de ferrocianuro potásico.El ferricianuro potásico se separa de la solución: 2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl Usos. Es utilizado como componente base en la preparación del reactivo de Drabkin, utilizado para pruebas cuantitativas de … Tīmeklis2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium ferrocyanide from a solution. [citation needed] A famous reaction … TīmeklisIn K4[Fe(CN)6] oxidation state of iron is +2.where as in K3[Fe(CN)6] oxidation state is +3. Since both have strong field ligand therefore pairing occur. in case of +2 oxidation state all electron is paired such that the configuration is T2g6. But in case of +3 oxidation state the configuration is T2g5.Hence K3[Fe(CN)6] more stable because Fe3+ is … rbi wireless
