WebJan 4, 2024 · Sulfur dioxide evolved as the reaction progressed. The reaction is sensitive to changes in H2SO4 concentration; 75-pct H2SO4 produced large amounts of H2S (fig. 2), and 87.5-pct acid yielded SO2 primarily (fig. 1). In these tests using an excess of acid, the optimum acid concentration to minimize sulfur gas evolution was about 80 pct.
