. In this experiment I perform the classic carbon pillar experiment whereby sugar (known as sucrose - C12H22O11) is dehydrated in the presence of concentrated sulfuric acid (H2SO4). As sulfuric acid has a high affinity for water, it removes it with an exothermic reaction. With sugar, the resulting product is carbon which rises out of the beaker due to porosity. You also get water (in the form of steam due to the exothermic reaction) and gaseous sulfur dioxide (which means do this in a fumehood or outdoors).
