Answer:
When heated, the pure 100% acid loses sulfur trioxide gas, SO3, until a constant-boiling solution, or azeotrope, containing about 98.5% H2SO4 is formed at 337°C. ... When hot it is an oxidizing agent, the sulfur in it being reduced; sulfur dioxide gas may be released
Explanation:
Sulfuric acid is a great proton source. In organic chemistry, H2SO4 and other acids can be used as acid catalysts for reactions like alcohol dehydration. ... Heating up the solution of dilute sulfuric acid is a necessary component to overcome the activation barrier needed for your particular reaction.
