Chemical Reaction of Sugar and Sulfuric Acid

In this video, Lonnie demonstrates a chemical reaction by mixing cane sugar with sulfuric acid. The sulfuric acid acts as a dehydrating agent, removing water from the sugar and leaving behind elemental carbon. This reaction is exothermic and results in the dramatic formation of black carbon. The video provides a step-by-step observation of the reaction, highlighting the expansion of carbon as it forms.
