Preparation of BaSO 4 by precipitation reaction by using given materials and the complete balanced equations for the reaction chosen should be written, Concept introduction: Precipitation reaction: The formation of the product is insoluble when the ions combine in the solution is called precipitation reaction. Acid - base reaction: Formation of the salt from the cation from the base and anion from the acid and formation of water is also the product. Gas forming reaction: The reaction of acid and metal carbonates which produce carbonic acid. The carbonic acid decomposes which gives water and carbon dioxide. Oxidation - reduction reaction: The electrons are transferred to one to other is called oxidation reduction reaction.
