CAS 10294-40-3

Barium chromate

Description:

Barium chromate, with the chemical formula BaCrO4 and CAS number 10294-40-3, is an inorganic compound characterized by its bright yellow color and crystalline structure. It is a salt formed from barium and chromate ions, and it is commonly used as a pigment in paints, plastics, and ceramics due to its vibrant hue and opacity. Barium chromate is insoluble in water, which contributes to its stability in various applications. However, it is important to note that it is considered toxic and a potential carcinogen due to the presence of hexavalent chromium, which poses environmental and health risks. The compound can be produced through the reaction of barium salts with chromic acid or chromate salts. In addition to its use in pigments, barium chromate has applications in the field of analytical chemistry as a reagent. Proper handling and disposal are essential to mitigate its hazardous effects, and safety precautions should be observed when working with this compound.

Barium chromate

CAS: 10294-40-3

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.
