An eggshell is mainly composed of the compound known as calcium carbonate. When calcium carbonate comes in contact with vinegar (acetic acid), it forms calcium acetate and bubbles of carbon dioxide gas.
But in the world of 13 year-old twin boys, it's more fun to see what happens when you drop the egg from the balcony and see what happens.
The eggs were placed in the solution for 4 days for observation, and then when the lesson was finished, they made their own eggsperiment!
lemme just ask how do i extract calcium carbonate from the eggshells?
