Be sure to specify states such as (aq) or (8). For example: The first of these formulae is just the other ones divided by two and rearranged a bit although the second one is easier to understand what is going on. Here is the equation for this double-replacement reaction. The name Iodine is derived from the Greek word "iodes" meaning violet. You can see that the reacting proportions are 1 mole of dichromate(VI) ions to 6 moles of iron(II) ions. Once again, notice that replacing water molecules by chloride ions changes the charge on the ion. (a) Kazuhiko Takai, K.; Loh, T.-P. "Chromium(II) Chloride" in Encyclopedia of Reagents for Organic Synthesis John Wiley & Sons: New York; 2005. One of the water molecules is replaced by a sulfate ion. The diiodide is then reiodinated. An excess of ethanol is added slowly with stirring so that the temperature doesn't rise too much. We nearly always describe the green ion as being Cr3+(aq) - implying the hexaaquachromium(III) ion. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum.
