Decomposition of Sugar by: Aniah fountain

What's Happening

In this experiment I will be combining sulfuric acid and sugar. The sulfuric acid will decompose the sugar into water and carbon, release heat and a charcoal like substance will rise into the air.

C12H2O (sugar)+ H2SO4 (sulfuric acid) => 12C (carbon, aka black stuff) + 11H2O (water) + H2SO4 (sulfuric acid)

Materials needed

  1. 96% sulfric acid
  2. 2 beakers
  3. white sugar
  4. plastic mixing tool
  5. Goggles
  6. Gloves


1. Put on safety goggles and gloves first. Sulfuric Acid is one of the most dangerous acids out there, make sure to be careful and have adult super vision over this project

2. Carefully poor 100mL of sulfuric acid in beaker #1

3. Measure 100mL of sugar in beaker #2

4. Now poor the sugar into the sulfuric acid and stir with plastic mixing tool

5. Once the liquid gets warm and slowly turns black stir carefully and watch the sulfuric acid and sugar rise into carbon


Combining sugar and sulfuric acid in this experiment resulted in two types of chemical reactions. A decomposing reaction (separation) as well as a exothermic reaction (heat). The two elements that make up sugar, carbon and water, became heated and then separated by the sulfuric acid. The carbon ascended in the air while the water stayed down below with the leftover sulfuric acid. This is what is also know as dehydration of sugar.
