Question

After removing the outer shell of the 2 eggs in dilute HCl one is placed in distilled water and the other in a saturated solution of NaCl what will you observe and why?

Answer 1

After a few hours, it will be noticed that the egg placed in water swells and the one in salt solution shrinks.Equilibrium is being established in both cases.

1. In the first case, water diffuses through the skin, a semipermeable membrane, into the egg material, which swells.
2. In the second case, the concentration so the salt solution being higher than the egg, the material shrinks.

Thus, Osmosis equilibrium results, whenever there are two parts of solution, separated by a semipermeable membrane.
