Particles can move. One type of movement is diffusion. Diffusion is when particles move from an area of higher concentration to an area of lower concentration. The particles can move throughout a liquid, an area , or through a semipermeable membrane. Diffusion can be facilitated or non facilitated. When no other factors are involved in diffusion the particles are moving down their concentration gradient so that the amount of particles can be evenly distributed. if proteins or helpers are involved the particles can move up their concentration gradient , making the concentration unequal. So, if i spray air freshener at one side of a room the particles will be excited and want to evenly distribute themselves throughout the room. So the particles

osmosis is when water diffuses across a semipermeable membrane. Osmosis happens in order to balance the concentration of solutions on either side of the membrane. An example of osmosis can be observed by placing a red blood cell into a solution. if the concentration of the solution the red blood cell is placed into has a higher concentration the water from the inside of the cell will move out. The water moves out of the cell in order to dilute the solution making it less concentrated.
In this experiment ,my group members and I used 0.04 M of a starch solution, Dialysis tubing , graduated pipettes , rubber band/dialysis clip, 250-ml beakers, Iodine, conductivity probe,and a computer with loggerpro software.
Before starting to gather supplies one of my group members logged into the computer and pulled up the loggerpro software.
Another group member opened the drawer at the table and set up the conductivity sensor, so it could work properly with the loggerpro program.
Next, we Obtained two , large graduated cylinders.
In the first cylinder one of my partners placed the 30 ml stock solution.
In the second cylinder I placed 20 ml of stock and 10 ml of …show more content…
My partner and I returned back to our table with the beakers and tubing.
My group members and I created a hypothesis on the outcome of the experiment.
Next we added 3 drops of Iodine to the each beaker we placed the dialysis tubing with the stock solution in one beaker
We waited 3 minutes and placed the conductivity sensor inside of the beaker. the loggerpro program recorded the results.
We did the same for the second beaker with the tubing containing the stock solution and water. Lastly we recorded the results with the conductivity sensor and loggerpro. The results for the lab were inconclusive. When my group members and I placed the conductivity sensor into either beaker, the reading did not fluctuate. Because the meter did not fluctuate, my group members and I came to the conclusion that the models we created were leaky models. I think we could have improved the outcome of the experiment in many ways. When my partner and I started to prepare the dialysis tubing we were unsure of how to tie the knots, so the knots were not as tight as they should have been. Instead of having different people tie the ends of the dialysis tubing we could have asked one group member to tie and prepare the tubing in order to have constant results. My group and I could have also improved on communication and interpreting the instructions. When pouring the solutions into
