Question

What happen when egg is first put in hydrochloride acid for for something and then placed in a concentrated salt solution?

Answer 1

When placed in HCl, the shell of egg made of CaCO3, dissolves in the acid and a thin membrane keeps the egg in shape.

When it is placed in a concentrated salt solution, the water inside the egg moves out of it through the process of osomosis. As a result, the egg shrinks.
