Solved: Sulfuric acid (H2SO4), the most important
Chapter 9, Problem 133P(choose chapter or problem)
Sulfuric acid \(\left(\mathrm{H}_{2} \mathrm{SO}_{4}\right)\), the most important industrial chemical in the world, is prepared by oxidizing sulfur to sulfur dioxide and then to sulfur trioxide. Although sulfur trioxide reacts with water to form sulfuric acid, it forms a mist of fine droplets of \(\mathrm{H}_{2} \mathrm{SO}_{4}\), with water vapor that is hard to condense. Instead, sulfur trioxide is first dissolved in 98 percent sulfuric acid to form oleum \(\left(\mathrm{H}_2\mathrm{S}_2\mathrm{O}_7\right)\). On treatment with water, concentrated sulfuric acid can be generated. Write equations for all the steps and draw Lewis structures of oleum based on the discussion in Example 9.11.
