In the following experiment we observed the effects of vinegar, water and syrup on an egg. This allows us to look in depth at the effects of diffusion and osmosis.

Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Osmosis is the diffusion of water across a selectively permeable membrane. In osmosis water always moves to the higher solute area.

When observing the effects that the egg undergoes, a hypotonic solution or a hypertonic solution can explain what you see. A hypotonic solution is a solution that has a lower concentration of solute, therefore a higher concentration of solvent inside the cell. The cell will expand as the liquid moves in because the molecules move from an area of high solvent concentration (outside the cell) to the region of lower solvent concentration (inside the cell). A hypertonic solution...
