Question

Question

  • Can you inflate a balloon without using your mouth?


Purpose

purpose

  • To observe the chemical activity of mixing baking soda with vinegar.


Hypothesis

Hypothesis

I believe that you can inflate a balloon without using your mouth because there are certain chemicals that may cause such inflation.


Materials

Materials

  • Baking soda

  • Empty soda bottle

  • Vinegar

  • Balloon

  • Straw or a funnel


Procedures

Procedures

  • Place two teaspoons of baking soda into the empty pop bottle

  • Add an inch of waterin the bottle

  • Next, place a tablespoon of vinegar into the balloon

  • Put 1tbs., 3 tbs., and 5 tbs. in three different balloons.

  • Cover the top of the bottle with the mouth of the balloon.

  • When the balloon is on correctly, lift the end of the balloon releasing the vinegar into the bottle where the baking soda and water waits

  • Watch what happens

  • Does the balloon expand? Does the balloon shrink?


Observation

Observation

  • With 1 tablespoon of baking soda, the balloon inflated very little.

  • With the 3 tablespoons of baking soda, the balloon inflated a lot more.

  • With the 5 tablespoons of baking soda, the balloon inflated a lot more and some balloons popped off the bottle.

DATA


Conclusion

Conclusion

  • My conclusion was correct! You can inflate a balloon without the use of your mouth. Why? Because when the vinegar reaches the baking soda, a chemical reaction takes place. During this reaction carbon dioxide is formed. This gas is released from its liquid/solid state which makes the balloon expand. See how large you can make the balloon by adding more baking soda, vinegar, and water.
