    • EFFECT OF VINEGAR ON RAW CHICKEN EGG Done By: Leow Wei Sheng 2P315

      • Reflection
    • HYPOTHESIS
      • The egg shell in vinegar will dissolve while the egg shell in plain water will not and the egg will become bouncy
    • WHY VINEGAR AND WATER?
      • Vinegar is used to represent liquids with weak organic acid while water is used to act as a control
    • MATERIALS USED
      • Two chicken eggs
      • Two identical containers
      • White vinegar
      • Water
    • 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
    • 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
    • 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
    • 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
    • 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.
