Today we started the diffusion through a membrane lab using eggs. Today's step involved measuring circumference and mass of an egg and submerging it in vinegar. What do you think will happen overnight??

I think the vinegar will start to dissolve the egg's outer shell, because the shell is composed of calcium carbonate and the acidity of the vinegar will dissolve it.
