Baking Soda + Vinegar = Bubbles
Dateline: 07/26/97
Chemical reactions occur when two chemicals unite or react to form a compound that is unlike the original substances and cannot be changed back to its original form. Chemical reactions are often accompanied by some sort of visible reaction. It's lots of fun to mix two every day ingredients and have such exciting results. Vinegar (acetic acid) and baking soda (sodium bicarbonate) create lots of bubbles. This is an experiment that you can do as often as you like and the same thing will always happen. Remember you should always do your projects with an adult!
Things You Will Need
- a squeeze bottle of vinegar
- a bowl of baking soda
- small spoons
- small cups
1. Place the materials on the table in front of you, drop a spoonful of the white powder in your cup. Squirt a little of the liquid onto the white powder.
2. Watch what happens!
3. Try this again using a few of the other cups.
Things to think about
What happened when you dropped the liquid on to the powder? Was it the same each time you tried the experiment? If there were differences what did you think caused them? Was it because of the amount of vinegar that was squirted, or how the powder was spread across the cup? Do you have any other ideas?
Could you find a way to make the most bubbles? What happens if you put the vinegar in first and then sprinkle the powder on top? Did you have fun using the sodium bicarbonate and acetic acid to make a chemical reaction?
Note: This is a typical chemical reaction in which an acid - vinegar, reacts with a base - baking soda, to produce a new chemical - a salt. The bubbles that form are full of carbon dioxide, a gas that is released in the process.

Note: The chemistry activity was inspired by the book More Mudpies to Magnets. Publishers Gryphon House, Inc. were nice enough to let me share their articles with you. Please visit their website. They have some great books for kids!
