Abstract
Many acid-base chemistry demonstrations and laboratory manuals include the "baking soda volcano". Others use the formation of calcium carbonate from calcium hydroxide and carbon dioxide in human breath. This demonstration uses principles from both as well as stoichiometry to answer the question "Does the order of mixing of reagents make a difference?" The demonstration is appropriate for introductory or high school chemistry, AP chemistry or general college chemistry.
