Planning Aim: to determine the concentration inside potato cells. What is the molarity? Prediction: In a strong solution the cylinder of potato will float and in a weak solution the potato will gain weight. I predict that in a solution the same concentration as the potato, it will not gain or lose weight. This is due to osmosis, water molecules travel from an area of high concentration to a low concentration through a semi-permeable membrane until they reach equilibrium. This means that if the potato is in a solution with the same amount of water as itself it will not float or sink. (The living world- pg 14, Michael Roberts) Apparatus: * Cork borer * Beaker * Potatoes * Scalpel * Sucrose solutions * Goggles & apron Method: * The apparatus is set up as shown in the diagram. * Six sucrose solutions of increasing molarity will be taken between 0.0M (distilled water) and 1.0M to try and find the molarity of...
