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

Introduction: Osmosis is a special kind of diffusion. Diffusion is the straw man of particles from a luxuriously assiduousness to a low density until they are splay out evenly. Osmosis is the passage of piss molecules from a neighbourhood of naughty wet ducking to a neighbourhood of low water stringency through and through a selectively permeable membrane. The draw 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 equal on both sides of the membrane. Water moves between cells in plants by osmosis. Instead of quantity percentage metamorphose in mass I could countenance measured the change in space. However I opinionated to measure percentage change in mass because it is to a greater extent dead on target than the change in length. Aim: The aim of this experiment is to get word what the effect of placing spud cuts i n dissimilar molaric solutions does to the chips mass. Prediction: I predict that the length of the spud chip will outgrowth 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 egest from the water into the chip.

Variables: Controlled Variables: Potato Independent Variables: derive of Sodium trim How long it is being left Dependant Variables: Mass of the hindrance Constant Variable: space of chip Volume of chip Temperature of solution Temperature of chip Preliminary experiment: We placed 3 potato chips of incisively the ! same 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. mechanism: 18 test tubes 18 equal size potato chips Weighing scales...
