Product Description
Barium chromate, named barium tetraoxochromate(VI) by the IUPAC, is a yellow sand like powder with the formula BaCrO₄. It is a known oxidizing agent and produces a green flame when heated, a result of the barium ions.
Application & Usage
A banana-color yellow pigment that is also called barium yellow. Barium chromate is precipitated from a Barium chloride solution by the addition of Potassium dichromate. Barium yellow is a fairly permanent pigment but it may turn green slowly in light.
Procedure
It can be synthesized by reacting barium hydroxide or barium chloride with potassium chromate. Alternatively, it can be created by the interaction of barium chloride with sodium chromate. ... 2 BaCrO4 + 2 H+ → 2 Ba2+ + Cr2O72− + H2O. Ksp = [Ba2+][CrO42−] = 2.1 × 10.
Notes
Barium carbonate is soluble in acid, including dilute acetic acid, in strong bases, and in aqueous ammonia.
