Chromium Quick inquiry Where to buy Suppliers range | Chromium. Uses: Chromium is oxidized readily in air forming a thin, adherent, transparent coating of Cr2O3. Chromium forms both the chromous (Cr2+) and chromic (Cr3+) compounds that are highly colored. Chromium metal reacts readily with dilute acids forming a blue Cr2+ (aq) solution with the evolution of hydrogen: Cr + 2HCl ? CrCl2 + H2 Chromium in metallic form and as Cr2+ ion are reducing agents. The Cr2+ reduces oxygen within minutes, forming violet Cr3+ ion: 4Cr2+(aq) + O2(g) + 4H+ (aq) ? 4Cr3+ + 2H2O (l) The standard redox potential for the overall reaction is 1.64V. Cr3+ ion forms many stable complex ions. In the aqueous medium, it forms the violet Cr(H2O)63+ ion which is slightly basic. Chromium(III) ion is amphoteric, exhibiting both base and acid behavior. Chromium reaction in an aqueous solution with a base produces a pale blue-violet precipitate having composition: Cr(H2O)3(OH)3. Cr(H2O)63+ (aq) + 3OH- (aq) ? Cr(H2O)3(OH)3 (s) + H2O The above precipitate redissolves in excess base: Cr(H2O)3(OH)3 (s) + H+ (aq) ? Cr(H2O)4(OH)2+ (aq) + H2O Chromium forms chromium(VI) oxide in which the metal is in +6 oxidation state. In acid medium it yields yellow chromate ion, CrO42-, and the redorange dichromate ion, Cr2O72-. Chromium is oxidized in nitric, phosphoric or perchloric acid forming a thin oxide layer on its surface, thus making the metal even more unreactive to dilute acids. Elemental chromium reacts with anhydrous halogens, hydrogen fluoride, and hydrogen chloride forming the corresponding chromium halides. At elevated temperatures in the range 600 to 700°C, chromium reacts with hydrogen sulfide or sulfur vapor, forming chromium sulfides. Chromium metal reacts at 600 to 700°C with sulfur dioxide and caustic alkalis. It combines with phosphorus at 800°C. Reaction with ammonia at 850°C produces chromium nitride, CrN. Reaction with nitric oxide forms chromium nitride and chromium oxide. 5Cr + 3NO ? 3CrN + Cr2O3. Group: Nanoparticles & Nanopowders.
