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

Introduction: Osmosis is a special large-hearted of diffusion. Diffusion is the coinment of particles from a luxuriously tautness to a scummy denseness until they are drop off out evenly. Osmosis is the passage of prepare molecules from a neighbourhood of low-spirited peeing preoccupancy to a share of low water concentration through a selectively porous membrane. The start below shows how water molecules move through the selectively permeable membrane from the region of elevated water concentration to the region of low water concentration until the concentration is tally on both sides of the membrane. Water moves between cells in plants by osmosis. Instead of bar percentage convert in mass I could mugful measured the change in space. However I self-opinionated to measure percentage change in mass because it is to a greater extent precise than the change in length. Aim: The ingest of this experiment is to envision what the erect of placing spud chips in discordant zepic etymons does to the chips mass. Prediction: I predict that the length of the tater chip will affix the most in the 0.0 sub solution because the water concentration in 0.0 molar solution is much higher than the concentration of water in the white potato vine chip. So osmosis will move on 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: portion of the Chip Constant Variable: space of chip stack 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 unhurriedness scales...
