acetic acid (vinegar) and calcium carbonate (eggshell) reaction - making the eggshell bubble and deteriorate as it disolves

The chemical reaction that occurs is
CaCO3 + C2H5O2H (acetic acid = vinegar) --> CaC2H5O2 + H2O + CO2
The shell is mainly CaCO3, Calcium carbonate, a hard crystaline compound.
CaC2H4O2, calcium acetate, is soluble in water, so it is removed from the shell. What is left of the shell becomes flexible as you only have the membranes left to hold the egg together.

The acid in the vinegar disloves the calcium in the egg.

Vinegar breaks down the enamel in the outer layer of the egg shell, and then rubberizes the membrane.

I think Alan Turing's chemical equation should read as follows:
CaCO3 + 2(C2H5O2H) (acetic acid = the acid in vinegar) -->
Ca(C2H5O2)2 + H2O + CO2

The reaction is basically the acid dissolving the calcium carbonate
CaCO3 + C2H5OOH ==> Ca(CH3COO)2 + H2O + CO2

the calcium in the egg shell is dissolved in the vinegar.

de-calcification, (removing the calcium out of the shell)
this produces carbon dioxide gas.
Also works with a chicken bone, if you leave it in a jar for a week or 3. the bone goes all floppy and soft.
