reaction between Sulphuric Acid and Glucose |
| This is a Dehydration reaction. Glucose is a carbohydrate, so the water is removed from the molecule, leaving with elemental carbon. The dehydration reaction is a type of elimination reaction. C6H12O6 (sugar) + H2SO4 (sulfuric acid) ? 6 C (carbon) + 6H2O (water) + mixture of water and acid Although the sugar is dehydrated, the water isn't 'lost' in the reaction. Some of it remains as a liquid in the acid. Since the reaction is exothermic, much of the water is boiled off as steam. |
