... going from a high concentration to a low concentration along a concentration gradient. The water moves out of the potato by osmosis going against a concentration gradient. Fair test I will make my experiment a fair test by using the same potato and by keeping the length of my potato chip the same and I will use measuring cylinders to measure out the water and sucrose solution. I will also leave the potatoes in the solution for the same amount of time. (10 minutes). Apparatus 1. Potato 2. Measuring cylinders 3. Water 4. Beakers 5. Sucrose 6. Weighing scales 7. Potato borer Variables The variable in my experiment is the concentration of water and sugar solution. The sugar solution is in molarity. I have changed the water and sucrose so they add up to 100ml.To make it easy to convert the sucrose in molarity. For example 100ml is 1 molar, 20ml is .2 molars and 30 is ...
