An egg swells in vinegar because of diffusion. The acetic acid of the vinegar reacted with the calcium carbonate in the egg shell. The vinegar will expand the shell as the carbon dioxide attempts to escape, because of a process called osmosis. When an acid and a base mix they form carbon dioxide which is a gas.
