    Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

    Name: Marion Paxton Diffusion Lab Introduction: In this lab you will observe the diffusion of a substance across a semi permeable membrane. Iodine is a known indicator for starch. An indicator is a substance that chances color in the presence of the substance it indicates. Watch as your teacher demonstrates how iodine changes in the presence of starch. **Prelab Observations: Describe what happened when iodine came into contact with starch. The cornstarch turned blue-black Procedure:

    The Effect of Osmosis on Potatoes/ Diffusion of Molecules through Benedicts Test of Dialysis dubing Introduction The focus of the lab on September 16‚ 2013 was Diffusion and Osmosis. Osmosis is a process in which the molecules of a solvent diffuse from an area of high concentration to an area of lower concentration‚ through a semipermeable membrane. Small solute molecules and water molecules can move freely through a selectively permeable membrane‚ but large molecules may pass through more

    Purpose: To see the effects of tonicity’s on potato cells. Background: Osmosis is the diffusion of water across a differentially permeable membrane due to concentration differences. Tonicity is the concentration of solutes. The potato cell has 3% of dissolved materials. Hypertonic is when the solution has more dissolved materials outside the cell than inside. The cell will lose water this way and shrink. The potatoes in the 5% salt solution will shrink. Hypotonic is when there is less solute dissolved

    Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions
