osmosis
...sotonic, and no diffusion is necessary. Osmosis is important because it helps determine how water and other substances are distributed in the body. Patients with edema, who retain water in their tissues, are injected intravenously with hypertonic solutions in order to draw the excess water out. In dehydrated patients, hypotonic solutions are used so that water will diffuse back into their cells. Brownian motion, which is a phenomenon that states that particles move randomly because they are being hit by other particles, is an important part of osmosis. It also states that temperature and size of the particle effect the rate of diffusion because of the kinetic energy of the particle (the more energy, the faster the rate). (2). In the first part of this experiment, dialysis bags which have been soaked in water overnight and have approximately the same concentration of solute in each will be placed in solutions with different concentrations of sucrose. The purpose will be to determine the concentration of solute in the dialysis bags. Based on the definition of Osmosis, it can be expected that if a bag is placed in a hypertonic solution, it will lose water (and therefore weight) because the water will move towards the region with the higher concentration of sucrose. If a bag is placed in a hypotonic solution, w...
