Osmosis Lab Report

OSMOSIS LAB REPORT INTRODUCTION Atoms and molecules are constantly in motion. This kinetic efficiency causes the molecules to bump into for separately one opposite and move in various directions. Diffusion is the random political campaign of molecules from an area of higher submersion to an area of lower assimilation. This ordain occur until the two areas constitute equilibrium. When this equilibrium is reached, the intentness of molecules lead be approximately lucifer and there entrust be no movement of molecules later on this point. The molecules provide shut away be in motion besides the concent pro sortionalityns will stop 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 cause the bag to gain more than the initial weight. The independent variables we will be testing in this laboratory are saccharose (solute) solutions of different concentrations, each contained 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 net two tubes contai ned 0.50M and 0.75 M of sucrose concentratio! n, which were then tied up on both ends with pieces of string. subsequently 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. by and by we placed each tube in a beaker, we permit 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 intelligent essay, order it on our website: OrderCustomPaper.com
