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

different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house. Osmosis is a vital mechanism in the transport of

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

different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would move from the

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

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
