The following are chemical properties of sulphuric acid:-It is acidic only in water solution when hydronium and sulphate ions are formed. Hydronium ions result in acidic property. It is diabasic as it ionises in two stages- 1 H2SO4 + H2O ↔ H3O+ + HSO4- 2 HSO4- + H2O ↔ H3O+ +SO42-1) It react with metals and form metallic sulphate and hydrogen at ordinary temperature. Mg + H2SO4→ MgSO4 + H22) It neutralises bases to form slats and water. CuO + H2SO4→ CuSO4 + H2O3) It liberates carbondioxide from metallic carbonate (ZnCO3) and bicarbonate(2NaHCO3). ZnCO3 + H2SO4 → ZnSO4 + H2O + CO24)It evolves hydrogen from metal sulphides. F2S + H2SO4 → FeSO45)It evolves sulphurdioxide and sulphites and hydrogen sulphites Na2SO3 + H2SO4→ Na2SO4 + H2O + SO2
