The contact process is used for the industrial production of sulfuric acid (H2SO4). In this process, sulfur dioxide (SO2) is oxidized to form sulfur trioxide (SO3), which is then dissolved in water to produce sulfuric acid. This is a crucial step in the large-scale production of sulfuric acid, an essential industrial chemical used in various processes such as the manufacture of fertilizers, detergents, and chemicals.
