The Effect of Glucose Concentration on the Rate of Osmosis Aims In this investigation Ill be working to know: How does the intentness of glucose vector sum affect the valuate of osmosis in white potato chips? Why does the soaking up of glucose solution affect the rate of osmosis in potato chips? How does the deal of potato chips changes in different concentration glucose solutions? Introduction The tendency of this investigation is to observe the factors that affect the rate of osmosis in potato chips and check out the pretendment of osmosis done the cells of potato. Diffusion Diffusion is the displace movement of particles from a voice of high-pitched concentration to a region of first base concentration until the concentrations are equal. The stimulate of diffusion depends n the disagreements amongst the concentrations to begin with. Osmosis is a special eccentric of diffusion, it occurs across a permeable membrane which allows so me particles to permeate through it and go along others. Therefore osmosis is the passage of water from a region of high concentration to a region of low concentration through a semi-permeable membrane.

The direction and the rate of osmosis depend on the difference in body of pull in concentration between the two sides of the membrane and this movement give continue until equilibrium is reached. Cell membranes will allow elfin molecules like oxygen or water or blow dioxide or glucose to pass through muchover they will counter larger molecules like sucrose or starch or protein to pass through. The te ndency of water to move through a partially ! permeable membrane is exposit as its water potentiality and is at a supreme in light water. As solutes are added the water potential lowers and this means that more concentrated solutions read lower water potentials than more put out solutions and so the water will have a greater tendency to move from pure water to any sedimentary solution and from a more dilute solution to a more concentrated solution.
