I will do this experiment twice to get an accurate answer. Prediction The passing through a semi-permeable membrane of high concentration and low concentration to an equal concentration is called Osmoses. Because of the balancing out of weight I predict that the weighted of the potato in the lower concentrations will increase and the weight of the potato in the higher concentration will decrease.
