Osmosis Investigation
Aims and Objectives
To determine the effect that varying salt concentration, in a solution, has upon the osmotic ability of potato chips of a given size.
Scientific Background Knowledge
Put simply osmosis is defined as the net movement of water molecules, across a selectively permeable membrane, from a dilute to a concentrated solution.
It is a special form of diffusion because it can only involve water molecules. However, it is not an isolated laboratory process. Many cell membranes behave as semi/selectively permeable membranes, and osmosis is a vital to their fu…
