Question

what happen when de-shelled egg is put in pure water

Answer 1

When we put a de-shelled egg in pure water nothing will happen, this is because there will be no result of movement of molecules as water is an isotonic solution (same concentration of solute and solvent).  

In comparison if the same egg goes under salt water its cells will swell because of endosmosis.

Answer 2

Answer:

The shell of an egg is a semi-permeable membrane that can allow water molecules and other small molecules to move in and out of the shell. When the egg is placed in pure water, water molecules will move into the egg through the process of osmosis causing the egg to grow lager
