Cyanide complexes of iron have been studied since the early eighteenth century primarily because of their value as pigments. However, a search of the literature reveals that only a small amount of work has been done on the particular species formed by iron (III) ion and hexacyanoferrate (III) ion. In these cases, the results of the various workers seem to conflict. Also, no one has yet sought to determine the natures of the colored species produced by mixing these ions in various compositions of an ethanol-water solvent. It was thought by the author that pH and spectrophotometric studies might be helpful in these areas.
