Osmosis Reprot

OSMOSIS REPROT Introduction Osmosis is the result of diffusion across a semi-permeable membrane. If two solutions of diametrical concentration are separated by a semi-permeable membrane, then the last result impart tend to diffuse across the membrane from the less backbreaking to the more concentrated solution. This process is called osmosis. This leads me to my question, how do varied concentrations of saccharose excise the rate of osmosis? My surmise is if sucrose concentration increases in the selectively-permeable dish antennagies then, the rate of osmosis get out also increase.Materials and Method To conduct this taste the materials needed are 3 different concentrated sucrose solutions, . 25 M, . 5 M, . 75 M. It will also require 4 beakers containing water from the sink. 4 pieces of dialysis tubing along with 8 pieces of string. An electronic balance to weigh the solutions. Makers and labeling type to label the different solutions. Paper towels needed to dry moody a ny excess water. This experiment should be conducted in a group of 3. Step 1.Fill quaternary separate beakers three-fourths full with deionized water. Step 2. Label the beakers to identify from each one different sucrose concentration later on. Step 3. Fill up the four baggies each with a different sucrose concentration, and the final bag fill up with deionized water. Step 4. Tie the bags with the string and rinse off each bag with di-H20 to wash away any spilt sugar. Step 5. numerate the solutions to determine the bag weight and then wait 35 minutes and repeat the weigh-in to get the final weight of the solutions. ResultsThe sign weight dupe was figured by weighing the baggie with the Sucrose solution before position it into the beaker with the deionized water, and after the baggies were in the beaker of deionized water for 35 minutes, then the baggies were weighed again. After the initial weight and the final weight was done, the final weight was divided by the initial weig ht and multiplied by atomic number 6 to get share of initial weight gain.

Discussion The hypothesis that I made earlier if sucrose concentration increases in the selectively permeable baggies, then osmosis would increase with it, was validated by this experiment. Different concentrations of sucrose changed the rate of osmosis. The final weight prove to be a fundamental gain.The line graph shows the greater the concentration of sucrose in the solution, the greater the weight gain. The weight gain also increases directly with the increase of sucrose in the solution which demonstrates osmosis. Even though my hypothesis was proven correct, on that point could have been a few lab errors that might of threw the initial and final weight gain off by an insignificant number. The baggies may non have been filled up exactly half way and things of that nature. In any case, the experiment proved a success as we got to stop osmosis taking place and results that occur from diffusion.
