How a Baking Soda and Vinegar Volcano Works
The baking soda and vinegar volcano is a popular science project, but
the science part of the project involves explaining how the reaction models a real volcano
or explaining the science behind the reaction that produces the lava.
In a nutshell, the reaction between baking soda and vinegar produces
sodium acetate, water, and carbon dioxide. The carbon dioxide is trapped
by detergent to form bubbly lava, which flows down the side of the
model because carbon dioxide is more dense than air. However, sometimes
you'll want to explain or write the chemical reactions that occur to
produce the carbon dioxide. Here's a look at ways to write the reactions.
