Osmosis Lab Report

OSMOSIS LAB REPORT INTRODUCTION Atoms and molecules are constantly in motion. This kinetic efficiency causes the molecules to bump into for apiece one some other and move in various directions. Diffusion is the random elbow grease of molecules from an area of higher submersion to an area of lower assimilation. This depart occur until the two areas constitute equilibrium. When this equilibrium is reached, the intentness of molecules leave be approximately lucifer and there allow be no movement of molecules later on this point. The molecules lead up to now be in motion besides the concent symmetryns will outride 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 create the bag to gain more than the initial weight. The independent proteans 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 terminal 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 embrasure 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. afterward we placed eac h tube in a beaker, we allow 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 salutary essay, order it on our website: OrderCustomPaper.com
