In our egg diffusion, we diffused the shell of the eggs and observed how osmosis effected the eggs. We put one egg in sugar water and the other egg in deionized water.
In the sugar water, the egg was hypertonic. It shrunk with a -42.17% change in mass, going from high concentration to low concentration, and had a -19.67% change in circumference. There is more solute outside the cell and more solvent inside the cell. The solvent tries to balance it by putting more solvent outside the cell, shrinking it.
The egg wants to maintain equilibrium, and in doing so, it has to have equal solute inside and outside. When the egg was placed in the vinegar, not only did the shell dissolve, leaving the membrane, but it shrunk with the increase of salt. When it was put into water, the water diffused, a type of passive diffusion, into the egg, enlarging it. After being put into salt, it shrunk.
This lab demontrates diffusion, highlighting hypertonic, hypotonic and isotonic. the egg clearly showed itself trying to reach equilibrium.
Fresh vegetables are sprinkled with water to make them grow and be larger. Roads are salted because it shrinks the water. The ice dissolves because it wants to have an equal amount of solute as the salt. In attempt to balance it, it dissolves.
I would create an experiment to test if there was an imbalance of solute and solvent. We discovered what happens when there is an imbalance of solute, so I'd like to see the next step.
