Product Information

• Name: Chromium(III) oxide
• Brand: Biosynth
• Description: Chromium oxide is a compound that exists in two phases, one of which is an oxide. It is a substance used to produce chromium metal and chromium salts. The oxide has been shown to react with the liquid phase of sodium carbonate to form a polymeric matrix. Chromium oxide particles can be used as an electrode material in flow systems for electrochemical impedance spectroscopy (EIS). Collagen, a major constituent of connective tissue, was found to bind chromium ions. This binding process may be due to the formation of hydrogen bonds between the collagen's carboxyl groups and the chromium ion's hydroxyl groups. The thermodynamic data for this reaction are given by: ΔH= -74 kJ/mol; ΔS = -120 J/mol·K; ΔG = -110 kJ/mol. Chromium oxide also reacts with potassium dichromate according to the following reaction mechanism: CrO + 2KCNO → 2CrNO
