Barium oxide (BaO) is formed by the oxidization of Barium salts such as barium carbonate, so the barium burns in oxygen to produce Barium oxide. Therefore, the chemical formula of Barium Oxide is BaO. The chemical reaction for the generation of Barium Oxide is as follows. 2Ba + O2 → 2BaO.

The oxidation and reduction reactions always occur simultaneously, such class of chemical reactions is named as the redox reaction or Oxidation-Reduction reaction. The substance getting reduced in a chemical reaction is known as the oxidizing agent, while a substance that is getting oxidized is known as the reducing agent.

Barite is ground into a fine powder and dissolved in sulphuric acid containing free sulphur xide. The solution is then poured into water and then it gets a precipitate of barium sulphate.

Barium is a naturally occurring alkaline metalloid element with atomic symbol Ba, atomic number 56, and atomic weight 137 that is only found in combination with other elements, typically barite (barium sulfate) and witherite (barium carbonate), or chemicals. Barium is used in many industrial processes, as well as in diagnostic testing, fireworks, and pesticides.

Barium sulfate is a soft crystalline solid. It is a rhombic crystal. The pure salt is white but the color of the mineral "barite" can vary between red, yellow, gray or green, depending on impurities. Its density is 4.50 g/cm 3 and its refractive index is 1.64. It melts around 1580 °C but decomposes above 1600 °C.

A chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms. Chemical reactions are represented by balanced chemical equations, with chemical formulas symbolizing reactants and products.
