The egg doesn't actually turn into rubber. The vinegar is an acid and the eggshell contains calcium carbonate which is a salt. The acidic vinegar breaks down the calcium carbonate of the shell (the calcium acetate is formed) and therefore dissolves it leaving only the thick membrane surrounding the hard boiled egg. It is only an egg without a shell.
The conclusion for many concerning the bouncy egg experiment is that vinegar does cause the egg to bounce. After soaking a raw egg in its shell in vinegar for a few days, the shell dissolves leaving just the rubbery membrane that can be bounced.
vinegar, letting it sit for 2-3 days
When you put vinegar in a naked egg the shell will decrease its shell then turning into a smelly egg
You can dissolve the calcium shell in vinegar (it takes a few days but is quite simple).
items: you will need... a jar with a lid, egg,and vinegar direction's: you put the egg in the jar and fill the jar with vinegar till the egg is covered. Then wait 3 days till u open you will see chunks of the shell coming off that is OK. Now 3 days have past and you open up the jar and you now have an egg with no shell! Does it feel squishy or slimy? cool right!
The chicken eggshell is 95-97% calcium carbonate with a stabilizing protein matrix. The shell can be dissolved by acids, including vinegar. If an egg is kept away from any acid attack, the shell can stay intact for years. If it is placed crushed and in contact with the ground, depending on soil acids, it may take weeks to months to disappear. If you are talking about an experiment at home soaking an egg in 4% acetic acid vinegar. . . it will take 24 hours to show good results and 36-40 hours for the entire shell to disappear.
What?After two days the egg shell will start to disintegrate (dissolve) and after a week the translucent membrane and the actual egg itself will be the only thing left. It will be rubbery and wrinkled.Why?The acidic content of the vinegar reacts with the calcium carbonate in the egg shell, and dissolves it. Because vinegar is only a weak acid the process takes some time.
it takes about ten days before it dissloves
When you leave an egg in vinegar for three days, the vinegar dissolves the eggshell due to its acidic nature. This process is known as osmosis. The egg will become rubbery and translucent as the acid breaks down the calcium carbonate in the shell, leaving the egg protected only by its membrane.
Well when I did my science project on this when i first I had 3/4 up of vinegar in a plastic cup put the egg into the vinegar you could see the acids from the vinegar and egg building up. On the second day, there was a lot of bubblie white stuff in the top of the plasic cup i had.
White vinegar is the best liquid for making an egg shell rubbery. The vinegar must be changed daily to prevent mold from growing on the egg shell.
Yes. Even dilute acetic acid, vinegar, can dissolve eggshell. Try this experiment: put a raw egg in vinegar for three days. The shell will dissolve but the egg will still be intact in its membrane. You can remove the egg and it will be rubbery. Handle delicately - the membrane is thin and easily torn. You'll also notice that the egg has swollen - the membrane is permeable, and the vinegar will penetrate into the fluid parts of the egg, swelling it.
