Dear student

Eggs are covered with a semi-permeable membrane, which allows water molecules to pass through. When you put a de-shelled egg into a salt water solution, water molecules pass from the egg, through this membrane, into the salt water solution … this will continue to happen till the water density on both sides is the same.

Since the egg is losing water, it will shrink. In other words, the egg is not actually losing any material … other than water.

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

Because the salt in the solution draws out the water in the egg, due to a difference in solute concentrations.

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. ... This is because, the cells of the membrane of the egg shell will be denatured by the heat and die off and will not allow water molecules to pass through it by osmosis
