Osmosis Lab Report

OSMOSIS LAB REPORT INTRODUCTION Atoms and molecules are constantly in motion. This kinetic efficiency causes the molecules to bump into for each one early(a) and move in various directions. Diffusion is the random pur larboard of molecules from an area of higher submersion to an area of lower assimilation. This bequeath occur until the two areas constitute equilibrium. When this equilibrium is reached, the intentness of molecules ordain be approximately lucifer and there lead be no movement of molecules later on this point. The molecules pull up stakes alleviate be in motion besides the concent proportionalityns will roost the same. With this project, I assumed that when a great amount of saccharose is added to water, then the concentration of that membrane would be hypnotic causation the bag to gain more than the initial weight. The independent variables we will be testing in this laboratory are sucrose (solute) solutions of different concentrations, each co ntained in a semi-permeable, cellophane membrane. The dependent variable is the rate of osmosis. The question is how does sucrose concentration affect the ratio of Osmosis? My hypothesis is as the sucrose concentration increases the rate of Osmosis will increase. MATERIALS & METHODS When conducting this experiment, we filled 4 presoaked tubes with glucose.

individually tube contained a certain amount of glucose in coordinate to distinguish a difference between each membrane number 1 tube contained 0M of sucrose concentration and the second strip, 0.25M of sucrose concentration. The last-place two tubes contained 0.50M and 0.75 M of sucrose concentration, which were then tied up o n both ends with pieces of string. subseque! ntly we secured all the tubes with strings at both ends, we filled up four beakers half port to the top with distilled water. We weighed each individual tube on an electronic balance and then we distributed them evenly among all four beakers. aft(prenominal) we placed each tube in a beaker, we let them soak for about 30 minutes. When the 30 minutes were up, we took each tube out of the...If you want to get a worthy essay, order it on our website: OrderEssay.net
