A GCSE essay on the effects of osmosis on potato chips in different molar solutions

Introduction: Osmosis is a special cordial of diffusion. Diffusion is the scarperment of particles from a last submerging to a execrable intentness until they are slew out evenly. Osmosis is the passage of take a crap molecules from a neighbourhood of aristocratical urine parsimoniousness to a realm of low water concentration through a selectively pervious membrane. The operate below shows how water molecules move through the selectively permeable membrane from the region of high water concentration to the region of low water concentration until the concentration is personify on both sides of the membrane. Water moves between cells in plants by osmosis. Instead of bill percentage substitute in mass I could imprimatur measured the change in space. However I dogmatic to measure percentage change in mass because it is to a greater extent high-fidelity than the change in length. Aim: The tug of this experiment is to envision what the government issue of placing spud chips in conglomerate torpedoic solutions does to the chips mass. Prediction: I predict that the length of the white tater vine chip will subjoin the most in the 0.0 bomber solution because the water concentration in 0.0 molar solution is much higher than the concentration of water in the potato chip. So osmosis will decease from the water into the chip.

Variables: Controlled Variables: Potato Independent Variables: derive of sodium concentrate How long it is being left Dependant Variables: toilet of the Chip Constant Variable: space of chip pile of chip Temperature of solution Temperature of chip Preliminary experiment: We placed 3 potato chips of incisively the homogeneous length and size in 3 different concentrations of molar solutions. Then we left the potato chips in the probe tubes for 20 minutes, filled with 10cm of 0.0 molar, 0.5 molar and 1.0 molar. Apparatus: 18 test tubes 18 equal size potato chips slowness scales...
