Transcript of Copy of Self-Inflating Balloon

Self-Inflating Balloon
Background Research
Procedure
1.Gather a water bottle, a small balloon, baking soda, and some vinegar.
2.Empty the water bottle and fill it a quarter way full of vinegar.
3.Stretch the balloon like you were about to blow it up.
4.Pour a table spoon(tbsp) of baking soda into the balloon. Shake it lightly until all of it reaches the bottom of the balloon. 5.Put the opening of the balloon over the opening of the water bottle, being careful not to get any of the baking soda in the vinegar.
6.Once the balloon is attached to the bottle, lift the balloon up and lightly shake the baking soda into the vinegar.
Cider vinegar inflates balloon the largest
Rice vinegar inflates balloon the smallest
White vinegar inflates balloon the
second largest
Results
Purpose/Problem
When you combine an acid and a base, they neutralize the reaction thus the formation of water and salt. The mixture of the acid and base produces heat, causing the water to become hot and boil. Sometimes it can even cause an explosion.

An acid creates a chemical reaction with the a base. When the two substances mix, you get carbonic acid, which is unstable and decomposes to become carbon dioxide and water. Since the carbon dioxide is much less dense than the acid and base that I used to create it, it wants to expand, and the balloon used in my experiment is stretchy enough to allow it to do just that.

If you mix an equal amount of acid and base, you get a material that is neither. Acids are neutralized by a base, so you get a neutral pH. Water and a salt are formed. On the other hand, if you mix a strong acid and a weak base, the end product would be acidic. If you mix a weak acid and a strong base, the end product would be basic salt.
The purpose of this project is to find out what happens when you mix an acid and a base

Any Questions?
When I mixed the acid(vinegar) and the base(baking soda) it creates carbonic acid, which is unstable and decomposes to become carbon dioxide and water.
Since the carbon dioxide is much less dense than the stuff I used to create it, it wants to expand, and the balloon is stretchy enough to allow it to do just that
Overall, my hypothesis was correct
Hypothesis
It will create a less dense air than the acid and base
I made this little note just for Ethan Fisher;
I FOUND THIS PROJECT ON THE
INTERWEBS!
You're welcome.
Materials
