Planning Experimental Procedures Preliminary Experiment For the preliminary experiment I used 3 cm long chips with an average mass of 4.2 grams (g). We only used two different concentrations of solution for this experiment, 1molar (M) and distilled water. We submerged the potato chips in 15mls of salt solution and left them for 15 minutes. Here are our results: Chips placed in concentrations Mass before Submersion Mass after submersion (15 mins) Salt (1M) 4.2 3.9 Distilled Water 4.3 4.5 The results that we got were much as I expected. From this however we did realise 15 minutes is not long enough for a lot of osmosis to take place. It was also evident...
