Biology students use raw eggs an experiment on tonicity and osmosis. students put their eggs into vinegar to remove the shelves. the vinegar was used to remove the shelf in the raw egg what other fax did vinegar have a egg

The vinegar removed only the shell of the egg because it was acidic. But it was unable to mess with the egg, because as it removed the shell of the egg, it was unable to get past the sac, the part that protects the inner egg. It is hard to puncture this sac, unless dropped or punctured by a nail or something hard.
