Required chemicals: barium carbonate, cheap potteries grade. hydrochloric acid, 10%. distilled water. hydrogen peroxide, 3%. May 29, 2024 ... When exposed to acids like hydrochloric acid (HCl), barium carbonate dissolves, producing barium chloride (BaCl₂) and carbon dioxide gas. Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: BaCO3 + 2 HCl → BaCl2 + CO2 + H2O Jan 21, 2022 ...
