Osmosis Lab Report

OSMOSIS LAB REPORT INTRODUCTION Atoms and molecules are constantly in motion. This kinetic efficiency causes the molecules to bump into for to each one one other and move in various directions. Diffusion is the random thrust of molecules from an area of higher submersion to an area of lower assimilation. This lead occur until the two areas constitute equilibrium. When this equilibrium is reached, the intentness of molecules allow for be approximately lucifer and there impart be no movement of molecules later on this point. The molecules go forth til now be in motion besides the concent dimensionns will die hard 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 changeables 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 final two tubes contained 0.50M an d 0.75 M of sucrose concentration, which wer! e 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 manner 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. afterwards 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 near essay, order it on our website: OrderCustomPaper.com
