Let's pretend we are exploring the osmosis and diffusion of potatoes. We are going to soak cubes of potatoes in six different solutions. Each solution will consist of a distilled water and NaCl (sodium chloride) mixture. Some mixtures will have a greater concentration of NaCl than others. We will leave each group of potatoes in the solutions for 30 minutes. We will weigh the potatoes before and after soak to determine a percentage change pre and post soak. Use the following formula: post-soak mass - pre-soak mass = increase/decrease, Increase/decrease ÷ pre-soak mass x 100 = % changed. In 0.0M NaCl pre-soak is 6g post-soak is 7.2g.
What trends did you notice?
