Question

When outer shell of two eggs is placed in a pure water and other is placed in a saturated solution of NaCl what will be observed and why.?

Answer 1

The egg placed in water will swallow due to endosmosis due to diffrence in concentration of protien and other egg that is in nacl solution will shrink due to osmosis

Answer 2

It is observed that there is an increase in the size of the egg kept in distilled water. This is because the solution inside the egg is concentrate and the liquid surrounding the egg is pure water. Because of the osmosis, the solvent flows from outside the egg towards inside the egg and the egg swells.

There is decrease in the size of the egg kept in NaCl solution. This is because the solution inside the egg is dilute. Because of osmosis, the solvent flows from inside the egg towards outside the egg and the egg shrinks.
