WebMay 9, 2024 · In view of the difficulty in measuring 0.272 mls of concentrated H2SO4, it would be recommended that you make a more concentrated solution first, and then make the final solution. Thus, you might make 0.5 M H2SO4 by diluting 27.2 ml concentrated H2SO4 to a final volume of 1 L, and then diluting this solution 1:100 (10 ml diluted to a … 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.

Because sulfuric acid is also a strong oxidizing agent, it oxidizes some of the alcohol to carbon dioxide and is simultaneously reduced itself to sulfur dioxide. Both of these gases must be removed from the alkene. Sulfuric acid also reacts with the alcohol to produce a mass of carbon. philadelphia thanksgiving day parade lineup

WebConcentrated sulfuric acid is a weak acid (see acids and bases) and a poor electrolyte because relatively little of it is dissociated into ions at room temperature. When cold it does not react readily with such common metals as iron or copper. When hot it is an oxidizing agent, the sulfur in it being reduced; sulfur dioxide gas may be released.
