Question

What happens when a de shelled egg is placed in water

Answer 1

Deshelled eggs are prepared by placing the egg in dilute HCL acid for 10 hours. Now the egg is covered with only semipermeable membrane. When this is placed in a salt solution (hypertonic solution), exosmosis occurs and the egg shrinks due to loss of water to the surrounding.   
If the water concentration inside the cell is higher than the surrounding medium, the medium is said to be hypertonic solution. Here, the number of water molecules diffusing out will be more than the molecules entering the cell.   The cell will shrink due to exosmosis.

Answer 2

when the de shelled egg is placed in hypertonic solution it will swell and when it is placed in hypotonic solution it shrink
