Write the reaction equation Ba-BaO-Ba (OH) 2-BaCO3-BaCl2-BaSO4
To obtain barium oxide from barium, we compose the equation for the reaction of barium combustion.
2Ba + O2 = 2 BaO.
BaO is a basic oxide, when interacting with water forms a base – barium hydroxide – Ba (OH) 2.
BaO + H2O = Ba (OH) 2.
Bases (alkalis) react with acidic oxides. We draw up the equation for the reaction of barium hydroxide with carbon monoxide (IV). Barium carbonate and water are formed. BaCO3 precipitates.
Ba (OH) 2 + CO2 = BaCO3 + H2O.
To get barium chloride, let’s draw up the equation for the reaction between barium carbonate and hydrochloric acid. Barium chloride, carbon dioxide and water are formed.
BaCO3 + 2HCl = BaCl2 + H2O + CO2.
Let’s compose the equation of the reaction between barium chloride and sulfuric acid. Barium sulfate and hydrochloric acid are formed. Barium sulfate precipitates.
BaCl2 + H2SO4 = BaSO4 + 2HCl.
