Combustion of Sucrose

C12H22O11 + 12O2 → 12CO2 + 11H2O

Overview

Sucrose (table sugar) burns in oxygen to produce carbon dioxide and water. When ignited directly, sugar burns slowly. However, when mixed with potassium chlorate or concentrated sulfuric acid, it reacts much more vigorously. The energy content of sugar is about 4 kcal/gram.

Everyday Example

The energy value listed on food labels (calories) is determined by measuring the heat of combustion of the food in a bomb calorimeter.

Industrial Importance

Bomb calorimetry of food products measures their combustion energy. Sugar combustion energy data is fundamental to food science and nutrition.
