Answer

The reaction between concentrated sulfuric acid and glucose involves the removal of water (dehydration) and the transfer of protons (acid-base chemistry). During dehydration, the sulfuric acid acts as a dehydrating agent, which facilitates the formation of carbon and water from glucose. Additionally, sulfuric acid, a strong acid, participates in acid-base reactions due to its capacity to donate protons to glucose. Therefore, the reaction can be accurately characterized as both dehydration and acid-base.
