O ácido clorídrico (HCl) presente no estomago da pessoa reage com o BaCO3 formando gás carbônico (CO2) e, assim, ocorre um deslocamento do equilíbrio da ... Barium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: BaCO3 + 2 HCl → BaCl2 + CO2 + H2O CHEMICAL CHARACTERISTCS ; Barium Carbonate (BaCO3). 99.2% min ; MOISTURE. 0.20% max ; Insoluble In HCL. 0.25% max ; Total sulfur as SO4. 0.25% max. Molecular Weight · 197.34 ; Appearance (Colour). White ; Appearance (Form). Crystalline powder ; Solubility (Turbidity) 10% solution in 3N HCl. Clear ; Assay (NaOH ... Since there is an equal number of each element in the reactants and products of BaCO3 + 2HCl = BaCl2 + CO2 + H2O, the equation is balanced. But if combined with sulfuric acid the solid barium carbonate will be covered in insoluble barium sulfate and the reaction will slow down or stop completely. Synthetic pathway of ...
