WebPyrosulphuric acid is also known as oleum. Its molar mass is 178.13 g/mol. It is an anhydride of sulphuric acid, is a colourless, crystalline solid and has a melting point of 36°C. It can be prepared by reacting excess sulphur trioxide with sulphuric acid. The reaction goes like this: H 2 SO 4 + SO 3 → H 2 S 2 O 7. WebNov 30, 2024 · Is H2S2O7 an acid or a base? Called oleum, it is a mixture of H2SO4 and SO3. The 1:1 mole ratio is where the formula H2S2O7 comes from, but it is not a distinct molecule, nor does it ionize in water to make H+ and HS2O7^-. Therefore, one cannot really call H2S2O7 an acid in the sense that H2SO4 is an acid. bonefish grill menu nutrition facts
