Making a Volcano Model

In a real volcano, molten rock (magma) from deep within the Earth erupts through a volcano. Our volcano model will erupt with a bubbly, fizzy liquid that is created by the interaction of an acid (vinegar) and a base (baking soda). Chemically, the acid and base neutralize each other, producing carbon dioxide gas as a byproduct. The exact reaction is:

HC2H3O2 (vinegar = acetic acid) + NaHCO3 (baking soda = sodium bicarbonate) = CO2 (carbon dioxide gas) + NaC2H3O2(sodium acetate) + H2O (water)
