Textbook Question
Chapter 15, Problem 15.164QP
Chicken egg shells are composed primarily of calcium carbonate, CaCO3. In a classic demonstration carried out in chemistry and biology classes, vinegar is used to remove the shell from an uncooked egg, revealing the semipermeable membrane that surrounds the egg keeping it intact. Refer to the Chemical Mystery “A Hard-Boiled Snack” at the end of this chapter to see a schematic diagram of a chicken egg. Estimate the minimum amount of vinegar required to remove the entire shell from the egg.
