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 other and move in various directions. Diffusion is the random movement of molecules from an area of higher submersion to an area of lower assimilation. This will occur until the two areas constitute equilibrium. When this equilibrium is reached, the intentness of molecules will be approximately lucifer and there will be no movement of molecules later on this point. The molecules will still be in motion besides the concentrations will remain the same. With this project, I assumed that when a great amount of sucrose is added to water, then the concentration of that membrane would be hypnotic causing 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 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 last-place two tubes contained 0.50M and 0.75 M of sucrose concentration, 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. After 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 respectable essay, order it on our website: Orderessay
