THE EGG IN VINAGER, RESULTS
A naked egg is an egg without a Shell. Using vinager, without breaking the menbrane that contains the egg. With this experiment we show the egg maybe is the biggest cell we have seen before.
The Shell will desapear because the vinager has an acid that do that reaction on the egg.
But the menbrane will be not affected.
When you submerge an egg in vinegar, the shell dissolves. Vinegar contains acetic acid, which breaks apart the solid calcium carbonate crystals that make up the eggshell into their calcium and carbonate parts. The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide—the bubbles that you see.
Each egg shell is made by a chicken and each one is feed in different way, the thickness of the egg Shell and calcium content, shape, mass can varies.
First, I put vinegar on a glass.
Then, I add an egg and left it for 3 days.
Finally I checked that the egg Shell had dissapeared.
I do not have calculations because we have not measured it before or later.
The eggshell disappear with the acid of the vinegar and it keep the membrane being a naked egg.

After 2 days the reaction of the egg in vinager. The eggshell is dissapearing.
