APPLIED SCIENCE ASSIGNMENT 2 TASK 1(A) Experiment on diffusion Aim: to determine diffusion (in ordinary tap water). Apparatus: beaker, potassium permanganate and tin foil. Method: I filled the beaker (half) with ordinary tap water and I released the potassium permanganate into it from the thin foil. Results: within a matter of a few seconds to one and half minutes, the whole water turned purple beginning from the area where the potassium permanganate was dropped. Conclusion: this experiment showed the movement of potassium permanganate molecule all around the beaker of ordinary tap water thereby, concluding the fact that molecules would move from a place of higher concentration to a place of lower concentration (diffusion) passively. Experiment on osmosis The aim of this experiment is to determine osmosis. Apparatus: test tube, potato tuber, electronic balance, watch glass, different concentrated solutions of sucrose: 0.003m, 0.006m, 0.125m, 0.25m, 0.5m, 1m and water. Method: I cut the potato in six equal parts and I weighed them...
