Question

What will happen if a deshelled egg is kept in saline water?

Answer 1

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