    No, only cola product drinks or white vinegar because they dissolve the egg shell.

    Can I use lemon juice to dissolve an eggshell?

    Yes, but I wouldn't advise it because It will make the egg explode and make a huge mess.
  • Question
    I would like to try adding dissolved eggshell to the tomato plants in my garden. Do you suppose that I could add some baking soda to the spent vinegar and then pour it into the soil?

    No. There are high chances of the soil to become acidic or basic, which can spoil the plant and the soil.

    I am doing a similar experiment to this to make a model, to see what an animal cell looks like. Every once in awhile, my egg floats to the top and rolls around in the cup. Is this normal?
    Community Answer
    That means that your egg is old; you need a fresher egg for it not to float above the vinegar or Coke.
  • Question
    What is wrong with the egg if the egg floats?
    Community Answer
    If your egg floats, it is too old. Try a fresher one that will remain at the bottom.
  • Question
    Why would doing this experiment be useful or important?
    Community Answer
    It shows two things: how acids work (vinegar is also known as acetic acid), and if you remove the shell, you can see the results of osmosis.
  • Question
    Is it okay to only leave eggshells in for two days to dissolve them?
    Community Answer
    If there are no more white spots (the remains of the shell), then you should be good. If there is any shell left, you may want to leave it in longer.
  • Question
    Can I use different types of vinegar when dissolving eggshells?
    Community Answer
    5% acetic acid, 7% acetic acid or 20% acetic acid can all be used. The higher the acetic acid content, the stronger the acid is, and it will dissolve the eggshells faster.
