Zhu, Guomin Lin, Zhong De Yoreo, James J. Regan, Annie Malinowski, Paul Jiang, Qianni Kluherz, Kyle T. ![]() "Structural Properties of Chromium(III) Iodide and Some Chromium(III) Mixed Halides". Kinetics and mechanism of the chromium(II)-catalyzed substitution of iodide ion in the iodopentaaquochromium(III) ion by water and by fluoride, chloride, and. Handbook of Inorganic Compounds, Second Edition. If 1.2981 g of lead (II) iodide was obtained in the analysis, what is the percentage of iodine in the original compound a. Ĭhromium triiodide was one of the first materials which was discovered to be a magnetic two-dimensional material that has great potentials for spintronics devices. A 3.1501 g sample of a compound that contains iodine is analyzed by precipitating all the iodine as lead(II) iodide. Ĭhromium triiodide can also be prepared as nanoplatelets from the alkoxide Cr(OC(CH 3)(C(CH 3) 3) 2) 3. Addition of small amounts of chromous iodide accelerates the dissolving process. Like CrCl 3, the triiodide exhibits slow solubility in water owing to the kinetic inertness of Cr(III). Ĭhromium triiodide is stable in contact with oxygen and moisture, but at temperatures approaching 200 ☌ it reacts with oxygen and releases iodine. To obtain high purity samples, the product is thermally decomposed at 700 ☌ to sublime out chromium(II) iodide. K2CO3(aq) + CrCl2(aq) CrCO3(s) + KCl(aq) Step two: balance the equation. Preparation and properties Ĭhromium triiodide is prepared by the direct reaction of chromium metal with an excess of iodine. When aqueous solutions of potassium carbonate and chromium(II) chloride are combined, solid chromium(II) carbonate and a solution of potassium chloride are formed. ![]() In this structure, chromium exhibits octahedral coordination geometry. Like the isomorphous chromium(III) chloride ( CrCl 3), chromium(III) iodide exhibits a cubic-closest packing arrangement in a double-layer crystal lattice. It is a black solid that is used to prepare other chromium iodides. Chromium(III) iodide, also known as chromium triiodide, is an inorganic compound with the formula Cr I 3. ![]()
