SpletTemperature dependent magnetic susceptibility studies of Fe(III) ions are ferromagnetically coupled with 3-D ordering occurring below 3.5 K and the appearance of the frequency dependent out-of-phase signal is explained in terms of an ordering with a spin glass-like behavior. A series of cyanide-bridged chain mixed Fe(III)/Ln(III) (Ln=Pr, Nd, Sm, Eu, Gd, … Splet15. avg. 2024 · Many metal ions form ferrocyanide precipitates, so potassium ferrocyanide is not a good reagent for separating metal ions. It is used more commonly as a confirmatory test. Potassium Ferricyanide Potassium ferricyanide will give a brown coloration but no precipitate with Fe3 +. With Fe2 +, a dark blue precipitate is formed.
