Question: How Much Hydrogen Peroxide do you need for foam to flow out f a 500mL bottle?
Hypothesis: You will need around 100mL of Hydrogen Peroxide for foam to flow out the 500mL bottle with detergent, yeast, and water added after the Hydrogen Peroxide.
Procedure: Step 1 measure a total of 100mL of Hydrogen Peroxide. Pour into the 500mL bottle.
Step 2 measure approx. 15mL of detergent. Pour into the 500mL bottle.
Step 3: Add 4-5 scoops of dry yeast into a testube containing 30-40 mL of water. Pour into the 500mL and watch the reaction.
Safety: Wear safety goggles and gloves when dealing with Hydrogen Peroxide.
Data: For the 2 experiments conducted, 1 of them used 50mL of Hydrogen Peroxide, and foam did not leave the bottle. For the second experiment, 100mL of Hydrogen Peroxide was used and this time foam flowed out the bottle.
Conclusion: The results did support my hypothesis. I found out that Hydrogen Peroxide mixed with detergent will create foam…Very slowly. You need yeast to act as a catalyst that will speed up the reaction to near instantaneous. Our results were reliable because everything was carefully measured and accurately documented.
