Chemical Reaction: Volcano Style

by Blake Smith

Why it Happens...

Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate (NaHCO3) and vinegar is an acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide.

What is happening?

Baking soda and vinegar react with each other because they exchange atoms. In this case, they are exchange a proton, which is a subatomic particle that makes atoms. You can also think of a proton as a Hydrogen atom that is missing an electron. In this reaction, baking soda acts as a base, and takes a proton from vinegar, which is an acid. The reaction releases gas because when the baking soda receives the proton, it transforms into water and carbon dioxide.
