Investigate the effect of different sucrose concentrations on potato chips.

Extracts from this document...


To investigate the effect of different sucrose concentrations on potato chips Introduction Osmosis is defined as the movement of water molecules across a partially permeable membrane from an area of high water concentration to low concentration. We are investigating this effect on potato chips, which are made out of many plant cells. Due to the fact that potato chips are consistent in type of cell, and are easy to work with, it makes them an ideal material for this type of experiment. When potato chips are immersed in water with a sucrose concentration, the water diffuses from the potato chip and into the stronger sugar solution. If this experiment is repeated with distilled water (has no sugar molecules) ...read more.


These included- * Temperature * Volume of solution * Size of chip (length and mass) * Type of potato * Sizes of equipment * Time potato chip is immersed in water * Range of the concentration of sucrose We concluded that the experiment should be conducted at room temperature (due to the fact that this is constant and easy to maintain), use 100cm3 of water, use a King Edward potato chip that is 10x10x30mm, in a boiling tube for 45 minutes. The sucrose concentration will vary from 0m (distilled water) to 1m. Apparatus list * x 11 10x10x30mm King Edward potato chips * 1100cm3 distilled water (100cm3 for each tube) * Tissue/ kitchen paper (to remove excess water) ...read more.


This will make it a fair test. Method 1. Gather all apparatus, sugar, water and potato 2. Dilute 1M of the sucrose-water into increments of 0.1 by adding 10ml of 1M, 90ml water to make 0.1M, 20ml 1M, 80ml water to make 0.2M and so on... Stir well 3. Cut potato into accurate 10x10x30mm chips and weigh to ensure they are equal (weight = xg) 4. Measure 100cm3 of the different strengths of sucrose-water solution and pour into boiling tubes, label as in diagram 5. Add potato chips at the same time and start timer immediately. 6. Leave chips for 45 minutes. 7. When 45 minutes is up, remove chips quickly and lightly dab on tissue/kitchen paper to remove excess water. 8. Measure and weigh chips, ensuring they do not get mixed up. 9. Note down results on a table similar to this: ...read more.

  1. Potato Chips

    Place each potato chip in a test-tube each containing 20cm� (this should be measured with a measuring cylinder) of a different sugar solution. a. Test-tube A: 0% (i.e. distilled water) b. Test-tube B: 5% sugar solution c. Test-tube C: 15% sugar solution d. Test-tube D: 20% sugar solution e.

  2. The aim of this experiment is to investigate the effect that different concentrations of ...

    I am going to ensure that the potato chip is completely covered in sucrose solution. The preliminary experiment showed that this gave the greatest change in weight from the potato therefore I will put it into practice in my actual investigation.
