    Osmosis in Potato Chips

    • 5 Pages

    GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

    experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato’s in water if they will not use them immediately. This allows the potato’s to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours. II. Objective: The reaction of the potato to the side submerged in water and the half excavated with salt. III. Raw Materials: Potato‚ Salt‚ Water‚ clear

    Lab Report INTRODUCTION: This experiment is being done to find out what happens to a carrot or a potato if you place them in two different solutions. Osmosis has a lot to do with this experiment and is the movement of water molecules from a higher concentration to a lower concentration. Osmosis only deals with water and is a type of diffusion. The difference between all three solutions is that in a hypertonic solution the cells fluid rushes out of the cell and causes it to shrivel. In a hypotonic

    Osmosis of Potato Cells

    Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

    Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

    Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue by submersing

    Osmosis in Potato Tissue Experiment  Background Information  Osmosis can be defined as the movement of water across a  semi-permeable membrane from a region of high water concentration to a  region of low water concentration.  The semi-permeable membrane allows small particles through it but does  not allow large particles such as sodium chloride. Osmosis will  continue until a state of equilibrium is reached i.e. there is no area  with a higher or lower concentration than another area

    Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

    Practical Work Nº2: “Different methods to control osmosis” Aim: observe and test the process of osmosis through different kinds of methods: the weigh (potato)‚ the density (beetroot) and under the light microscope (onion). Hypothesis: according to the encyclopedia definition osmosis is the diffusion of a liquid (most often assumed to be water‚ but it can be any liquid solvent) through a partially-permeable membrane from a region of high solvent potential to a region of low solvent potential. Thus

    Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being
