Background Info
When the two substances (vinegar and baking soda) mix, the vinegar, an acid, is creating a chemical reaction with the baking soda, a base. When the two substances form, it creates carbonic acid.
When the two substances become a carbonic acid, it is unstable and decomposes to create carbon dioxide and water. The carbon dioxide is less dense than the original materials, causing it to expand.
The balloons are used to collect the carbon dioxide, which inflates the balloons. People of any age who have problems with blowing up balloons can do an easy, fun project that will inflate balloons right for them. This project can also be used for a fun experiment to do at home with an older sibling or guardian.
Question
The question I am going to try and answer with an experiment is: How can we inflate a balloon by mixing an acid and a base?
Variable
The independent variable (what I will be changing in the experiment) in the project is the balloon size (lg., med., or sm.)
The dependent variable (what I will be measuring or observing) in the project is the balloon’s growth/inflation from the mixture.
The controlled variable (what I will be keeping the same during the experiment) in this project is the amount of vinegar and baking soda put in and what type of water bottle I will be using.
Hypothesis
If I mix an acid with a base, then the mixture will be able to inflate a balloon.
Materials & Procedures
My needed materials are:
Test tube (water bottle)
Vinegar
Small balloon
Medium
