When an egg is placed in a solution, water molecules will move into or out of the egg through the process of osmosis. This movement of water will cause the egg to change in mass. The direction and extent of the change in mass will depend on the concentration of the solution.

Hypertonic Solution

If an egg is placed in a hypertonic solution, the concentration of solute particles in the solution will be higher than the concentration of solute particles inside the egg. This will cause water molecules to move out of the egg and into the solution. As a result, the egg will lose mass.

Hypotonic Solution

If an egg is placed in a hypotonic solution, the concentration of solute particles in the solution will be lower than the concentration of solute particles inside the egg. This will cause water molecules to move into the egg from the solution. As a result, the egg will gain mass.

Isotonic Solution

If an egg is placed in an isotonic solution, the concentration of solute particles in the solution will be the same as the concentration of solute particles inside the egg. This will cause no net movement of water into or out of the egg. As a result, the egg will remain the same mass.

Importance of Osmosis in Eggs

Osmosis is an important process in eggs because it helps to maintain the proper water balance of the egg. If an egg loses too much water, it will become dehydrated and the embryo will not be able to develop properly. If an egg gains too much water, it will become waterlogged and the embryo will not be able to breathe.

Osmosis also plays a role in the hatching of eggs. When the embryo is ready to hatch, it will secrete an enzyme that breaks down the shell. This will allow water to enter the egg and cause it to expand. The expansion of the egg will cause it to break out of the shell.
