Vinegar Volcano
This classic science experiment can help demonstrate a simple chemical reaction. Vinegar contains acetic acid and baking soda is also called sodium bicarbonate. This reaction will result in carbonic acid; however, carbonic acid is unstable and will want to immediately break down into water and carbon dioxide (NaHCO3 + HC2H3O2→ NaC2H3O2 + H2O + CO2). Carbon dioxide is both the gas we breathe out and the gas that causes our sodas to fizz. The eruption in this experiment is the same kind of fizz and the leftover solution in the bottle is water. Food coloring can be added for fun and dish soap can be added to capture more of the carbon dioxide for a foam-like effect.
