Tonicity, which is directly related to the osmolarity of a solution, affects osmosis by determining the direction of water flow.
In a hypotonic solution, the extracellular fluid has a lower osmolarity than the fluid inside the cell; water enters the cell.
In a hypertonic solution, the extracellular fluid has a higher osmolarity than the fluid inside the cell; water leaves the cell.
The egg shell was dissolved in vinegar: this chemical equation shows what happened.
CaCO3+ 2H+ -> Ca+2 + H2O +CO2
Before we put the eggs in the solution, we thought that the effects of the hypertonic solution would shrink the egg, and the effects of the hypotonic solution would make the egg grow.
In conclusion, our predictions about the eggs were true. In the hypertonic solution the egg did not shrink and in the hypotonic solution the egg did grow.
