In Anson’s latest experiment, he shows us how to inflate a balloon using just some baking soda, vinegar and a water bottle.
This fun experiment shows how gas is often produced during chemical reactions. The gas produced when baking soda and vinegar are combined inflate the balloon.
Here’s what you’ll need for this experiment:
- 1 balloon
- 1 plastic water bottler
- 1 funnel
- 2 tablespoons baking powder
- 4 ounces vinegar
Here’s what you’ll need to do to conduct this experiment. It helps to have an adult around to supervise and help with some of the tricky parts of this experiment:
- Using a funnel, add 4 ounces of vinegar to a plastic water bottle
- Use the same funnel to add 2 tablespoons of baking soda into the balloon
- Carefully stretch the opening of the balloon over the opening of the water bottle
- When the balloon is fit over the bottle, hold the top of the balloon upright so the baking soda falls into the vinegar
- Watch the chemical reaction happen and inflate your balloon!
So what exactly is happening inside the water bottle to produce all those bubbles?
It helps to start with a basic explanation of chemical reactions. Everything around us is made up of molecules, including vinegar and baking soda.
Vinegar, also known as acetic acid and water, is acidic. While baking soda, also known as sodium bicarbonate, is a base.
Acids and bases partially break down into new substances when they come in contact each other in a process called neutralization. In the case of vinegar and baking soda, the new substances formed are water, a type of salt and carbon dioxide.
In the experiment above, the balloon inflates because of all the carbon dioxide that is released in the reaction.
After the only substances left behind after the reaction are known as neutral substances. They are neither acids nor bases.
The chemical formula for combining vinegar and baking soda is:
NaHCO3(aq) + HC2H3O2(aq) → NaC2H3O2(aq) + H2O(l) + CO2(g)
