  • 1. EFFECT OF VINEGAR ON RAW CHICKEN EGG Done By: Leow Wei Sheng 2P315
  • 2. CONTENT
    • Hypothesis
    • Materials used
    • Method
    • Results
    • Explanation
    • Conclusion
    • Reflection
  • 3. HYPOTHESIS
    • The egg shell in vinegar will dissolve while the egg shell in plain water will not and the egg will become bouncy
  • 4. WHY VINEGAR AND WATER?
    • Vinegar is used to represent liquids with weak organic acid while water is used to act as a control
  • 5. MATERIALS USED
    • Two chicken eggs
    • Two identical containers
    • White vinegar
    • Water
  • 6. METHOD
    • Pour vinegar into one of the containers and water into the other container
    • Immerse one raw chicken egg into each of the container
    • Leave the setups at one corner and observe after two days
  • 7. RESULTS
    • The eggshell of the egg in the vinegar dissolved while the eggshell of the egg in water did not
    • The egg without an eggshell was able to bounce
  • 8. EXPLANATION
    • Eggshell is made up calcium carbonate, and the vinegar is a weak organic acid, ethanoic acid
    • When carbonate reacts with an acid, the products will be soluble salt, carbon dioxide and water
    • Thus the shell slowly dissolves
    • The only thing left holding the shell together is the egg membrane, which is flexible and stretchy, so the egg is able to bounce
  • 9. CONCLUSION
    • The egg shell dissolved as acid reacted with calcium carbonate, which is the eggshell
    • The egg without an eggshell bounces as the membrane holding it is flexible and stretchy
  • 10. REFLECTION
    • After doing this experiment, I found out how to make an egg bounce and the effect of acid on calcium carbonate. I also learnt how to manage time better, as I had to manage between this experiment and school work, especially when this time is an examination period and I also had to study.
