Question

Biology students used raw eggs in an experiment on tonicity and osmosis. The students put their eggs into vinegar to remove the shells. The vinegar was used to remove the shell form the raw egg. What other effect(s) did the vinegar have on the egg?

Answer 1

The vinegar turned the white part of the egg clear, so you can see into it.

Answer 2

The egg swells up. The movement of particles from its higher concentration to the lower concentration through a semi-permeable membrane is known as osmosis. As the vinegar outside the egg has higher concentration of water molecules than the concentration of water molecules inside the egg hence to maintain the equillibrium, water molecules move inside the egg from the vinegar, which results into the swollen egg.
