Determining the Rate of Osmosis through a Semi-Permeable Membrane Schneider‚ Justin* Sec 16 and Thomas Hudson Introduction Water is the principle solvent in cells. There are three conditions that a cell may be subjected to in the cells physical environment. The cells may be isotonic‚ hypotonic‚ and hypertonic. Isotonic is when the cell and is environment have equal concentrations of solutes. Therefore cells in an isotonic solution do not experience osmosis. When the cell is hypotonic it

June 30th‚ 1940 changed the lives of everyone living on Guernsey. During World War II the Germans occupied the Channel Islands‚ Guernsey included. My book‚ The Guernsey Literary and Potato Peel Society‚ is an excellent example of historical fiction for three reasons‚ it tells about the occupation of the Channel Islands‚ how the islanders had to adapt their life during the occupation‚ and how their lives were changed because the occupation. “Late in the afternoon of June 28‚ 1940‚ six Heinkel bombers

retains the solids and contaminants in the water. The membrane is the most important part of the system. It very hard to located problems in the membrane. In addition‚ if the membrane is not in perfect condition‚ the system is not working. Reverse osmosis is a kind of filtration. Filtration is an oldest process that consists in the water passing through sand‚ gravel or membrane. Thus prevent the solids and contaminates passing for the other side. The pores of the filters need to be small. The smaller

Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and Surface area to volume ratio. Temperature can affect the rate in which a solute dissolves in a solution‚ higher temperature faster rate of Osmosis. This is caused by the molecules movements being faster

The effects of osmosis on potatoes placed in different salt concentration Introduction: Osmosis is a movement of water across a semi-permeable membrane. This may only happen when there is a difference in concentration between the two sides of the membrane. The water moves from low concentrations to high concentrations. That is because the low concentrated area tries to dilute the opposite via osmosis. The effects osmosis has on a cell are either that it becomes turgid and hard as water enters

investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying
