It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water

If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis.

The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH
