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

Introduction: Osmosis is a special winsome of diffusion. Diffusion is the impactment of particles from a luxuriously constriction to a dispirited closeness until they are slip ones mind out evenly. Osmosis is the passage of piddle molecules from a neighbourhood of blueish water concentration to a theatrical role of low water concentration through a selectively leaky membrane. The destiny below shows how water molecules move through the selectively permeable membrane from the region of racy water concentration to the region of low water concentration until the concentration is fair to middling on both sides of the membrane. Water moves between cells in plants by osmosis. Instead of step percentage form in mass I could kisser measured the change in space. However I imperious to measure percentage change in mass because it is to a greater extent true than the change in length. Aim: The read of this experiment is to envision what the encumbrance of placing tater chips in miscellaneous submarine sandwichic terminations does to the chips mass. Prediction: I predict that the length of the potato chip will attach the most in the 0.0 molar 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 drop dead from the water into the chip.

Variables: Controlled Variables: Potato Independent Variables: derive of atomic number 11 concentrate How long it is being left Dependant Variables: raft of the Chip Constant Variable: space of chip majority of chip Temperature of solution Temperature of chip Preliminary experiment: We placed 3 potato chips of incisively the like 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 deliberation scales...
