Fizzy Acid-Base Reaction
Instructions for Experiment using Vinegar as an Acid:
Instructions for Experiment using Lemon Juice as Acid:
STEM:
In this experiment, we mix baking soda (also known as sodium bicarbonate) which is a base with vinegar which is an acid. A base is any chemical substance that has a pH of less than 7 and an acid is a substance with a pH of greater than 7. When the two mix, the acid releases hydrogen protons and the base accepts these protons to form hydroxide. This chemical reaction generates carbon dioxide gas which produces the fizzing bubbles you see. You can also do the experiment with lemon juice which is another weak acid that will react with the baking soda.
