GENERAL INTRODUCTION TO THE CHEMISTRY OF DYES
Unlike most organic compounds, dyes possess colour because they 1) absorb light in the visible spectrum (400–700 nm), 2) have at least one chromophore (colourbearing group), 3) have a conjugated system, ie a structure with alternating double and single bonds, and 4) exhibit resonance of electrons, which is a stabilizing force in organic compounds (Abrahart, 1977)Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O These compounds exist most commonly as the heptahydrate (x = 7) but are known for several values of xThe hydrated form is used medically to treat iron deficiency, and also for industrial applicationsIron(II) sulfate Wikipedia

How to Write the Name for Fe2O3: Iron (III) Oxide
Feb 27, 2015· Writing the name for Fe2O3 is a bit more challenging since Fe is a transition metal This means you need to use parenthesis and Roman Numerals to show the charge onThe pigment Prussian blue consists of iron cations, cyanide anions, and water The empirical formula—minus the water of crystallization—is Fe 7 (CN) 18 This seems odd with respect to the iron oxidation state until you learn that the complex contains Fe (II) and Fe (III) Thus, the formula that gives a truer idea of its composition is Fe 4Prussian blue American Chemical Society
