Vinegar and Calcium Carbonate Reactions

Pat Horne from the Lakeshore Museum Center presents a simple science experiment that can be done at home using vinegar and rocks. The experiment involves testing rocks to see if they contain calcium carbonate by observing if they bubble when vinegar is applied. This reaction is similar to the one between baking soda and vinegar. The video explains how to set up the experiment, conduct it, and understand the results, highlighting the chemical reaction that occurs when vinegar interacts with calcium carbonate in rocks or shells.

What materials are needed for the vinegar and rocks experiment?

• Vinegar, sand, clear glasses, straw, and a spoon

• Vinegar, rocks, clear glasses, straw, and a plate
