I believe it the difference in the Ph factor between your mouth, primarily the tongue, and the soda. That's the culpit that makes your eyes burn when you get soap in them, or sometimes even plain water. Usually the difference isn't that great and the sensation quickly abates. Of course w/ the soap in the eye it's usually more acute and the burning lasts much longer because soap tends to have a higher Ph.
