Reaction of b2o3 with hf and con. h2so4
WebNov 4, 2024 · Therefore any reaction which occurs must be between the hydrogen sulfate ion, HSO 4– and the hydrogen carbonate ion, HCO 3–. Both HSO 4– and HCO 3– are amphiprotic, and either could act as an acid or as a base. The reaction between them is thus either HCO 3 − + HSO 4 − → CO 3 2 − + H 2 SO 4 or HSO 4 − + HCO 3 − → SO 4 2 − + H 2 … WebJan 25, 2015 · B + H2SO4 = B2O3 + SO2 + H2O Boron react with sulfuric acid 2B + 2H 2 SO 4 B 2 O 3 + 3SO 2 + 3H 2 O [ Check the balance ] Boron react with sulfuric acid to produce …
