Produktinformation

• Name: Barium chromate
• Marke: Biosynth
• Beschreibung: Barium chromate is a compound that is used as an oxidation catalyst in industrial processes. It is a white solid with a metallic luster and a high melting point. When barium chromate is heated, it decomposes to form barium oxide, carbon dioxide and oxygen gas: br> BaO + CO2 + O2 → BaO + CO br> Barium chromate can be prepared by reacting barium hydroxide with chromic acid or by heating the combination of calcium stearate, sodium carbonate and hydrochloric acid. The linear regression analysis of the activation energies for the oxidation reactions has been shown to be dependent on the concentration of polycarboxylic acid in the test samples, which may be due to an increase in hydrogen ion concentration. This increase in hydrogen ion concentration leads to increased rates of reaction between barium ions and polycarboxylic acids.
