BaCl2 + H2SO4 = BaSO4 + 2HCl HCl acid does not play any active role here. 10 years ago. BaS + 2 HCl → BaCl 2 + H 2 S. In place of HCl, chlorine can be used. COVID-19 is an emerging, rapidly evolving situation. Source(s): School. Still have questions? Uses. Although inexpensive, barium chloride finds limited applications in the laboratory and industry. no precipitate will form because Na2SO4 is soluble in water. a precipitate will form because BaSO4 is insoluble in water. 3 0. Ask Question + 100. A white precipitate of barium sulphate will be formed by the instant reaction between barium chloride and sulphuric acid. These basic salts react with hydrochloric acid to give hydrated barium chloride. Firstly the HCl will not react. Get more help from Chegg . a) What unknown element precipitate with Alcl3 (white), Bacl2 (white), Hcl(white), Ki (white), Na2co3 (white), NaOH (blue), and turns orange with the universal indicator? Alan F. Lv 6. Cheers. Barium chloride | BaCl2 | CID 25204 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. I assume you want the whole equation. Also, just out of interest, if it were a few mL of dilute H2SO4 solution being added to a block of BaCl2, would HCl be evolved as a gas? When 3 M HCl and 0.1 m BaCl2 are added to a solution of Na2SO4 no precipitate will form because BaSO4 is soluble in water. Barium chloride can in principle be prepared from barium hydroxide or barium carbonate. b) What unknown element precipitate with BaCl (white), AgNO3 (white), creates gas with H2SO4, HCl… Join Yahoo Answers and … BaCl2(aq) + Na2SO4(aq) + HCl = BaSO4(s) + 2NaCl(aq) + HCl. BaSO4 is insoluble in HCl. BaCl2(aq) + Na2SO4(aq) --> BaSO4(s) + 2NaCl(aq) 2 0. If BaCl2 were solid being added to dilute H2SO4 solution, would it be more correct to write +2HCl(aq) or + 2H+(aq) + 2Cl-(aq), since HCl completely dissociates in solution anyway? Info: BACl2 might be an improperly capitalized: BaCl2 Info: BACl might be an improperly capitalized: BaCl Instructions and examples below may help to solve this problem You can always ask for help in the forum Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. a precipitate will form because Na2 SO4 is insoluble in water. Get your answers by asking now. The reaction will occur with or without the presence of HCl.
