Investigating the Effect of Different Concentrations of Sugar Solutions on Potato Chips

Aim: -

To investigate the effect on potato chips in different concentration of sugar solutions.

Introduction: -

Osmosis is the net movement of water molecules from a region where there is a higher concentration of water molecules to the region where there is lower concentration of water molecules. The water molecues move through a partially permeable membrane, which allows the smaller molecules to pass but not the big ones. The diffusion of molecules from the region of higher concentration to the region of lower concentration until the concentration of water molecules has become same in both the areas.

Precautions to make the test fair:

For a fair test certain factors had to be kept in mind. I decided to choose sugar solutions of different concentrations so that I get different sets of result containing information about the change in mass, change in length and the mass and length of potato chips after the experiment. If any of the factors were not kept constant it would mean that the test is not fair. Such as: -

· All the potato chips have to be of the same length so that the area at which osmosis occurs is the same.

· Doing all the tests at one temperature will control the temperature. For the purpose of my experiment I am going to do all the experiments at room temperature.

· I will use the same potato so that the potential to absorb water is same.

· The mass of the chips of the potato will be same so that the test is fair. Mass will be measured in grams. The potato chip will be measured before it is put in the solution, and after is I taken out of the solution. This will allow us to see whether osmosis has taken place, and to what extent.

· The amount of solution should be same in each of the solutions.
