After observing how an onion membrane reacts when in contact with distilled water and with sodium chloride, we noticed that the NaCl pulled the membrane (cytoplasm) away from the cell wall. We think this is because the molecules of the NaCl are moving at a faster rate against the cell wall molecules than that of the distilled water, which caused the molecules of the cell wall to clump together in the middle.

Question: What would happen if we used a higher percentage of NaCl?
