A hypotonic solution has a lower solute concentration compared to the solution inside the cell. When a cell is placed in a hypotonic solution, water molecules will move from the solution to the cell to dilute the solute concentration. This process is known as osmosis.




Before placing the deshelled boiled egg in a hypotonic solution, the egg has a semi-permeable membrane that regulates the movement of water and solutes in and out of the egg. The membrane also helps to maintain the shape and integrity of the egg.


When the deshelled boiled egg is placed in a hypotonic solution, water molecules will move from the solution into the egg through osmosis. Since the egg has no shell, the water can freely move in and out of the egg. As a result, the egg will start to swell and increase in size as the water moves into the egg.


The egg contains a higher solute concentration than the hypotonic solution, and therefore, the water moves from an area of high concentration (solution) to an area of low concentration (egg). The water moves through the semi-permeable membrane of the egg to balance the solute concentration. This movement of water causes the egg to swell and increase in size.


In summary, placing a deshelled boiled egg in a hypotonic solution will cause the egg to swell and increase in size as water moves into the egg through osmosis. This effect occurs because the egg has a higher solute concentration than the hypotonic solution.
