The absorption spectra of aqueous solutions of ferric chloride have been examined qualitatively by Jones and Anderson, and quantitatively by Ewan, but Ewan's measurements were confined to very dilute solutions. It was thought, therefore, that quantitative measurements might profitably be carried out on more concentrated solutions of ferric chloride and on solutions of other salts of iron.
