Sucrose solution

By definition, osmosis is the process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. In other words, osmosis is the dissemination of water through a particular absorbing membrane from a higher focus to a lower fixation. There are a wide range of components that can influence the rate of osmosis, for example, temperature, molecule measure,

Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment, its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic) than the intracellular environment

concentration of sucrose solution affects the mass of the potato chip left in the solution for one day. Prediction I predict that when the sucrose concentration is low the potato chip will gain mass. This is because there will be a higher sucrose concentration in the potato chip so water will go into the potato from the solution. I predict that when there is a high concentration of sucrose the potato will lose mass. This is because there is a higher concentration of sucrose solution in the solution

either side of the membrane. Water molecules may move in and out of the cell, but there is no net diffusion of water. Water will move in one direction or the other, and this is determined by the solute or solvents concentration levels. If the two solutions are of equal concentrations, they will be isotonic. If the concentrations are unequal, the

concentration of Sodium Chloride (NaCl) and Sucrose. By making solutions of NaCl in water at different concentration, we found that the saturating concentration NaCl is between 0.375g/ml and 0.500g/ml. Using the same method, we found that the saturating concentration of sucrose is 0.750g/ml. Moreover, to further our understanding of density, we created a discontinuous density gradient using different concentration of sucrose solutions. When we placed the solutions in the test tube according to their relative

If a plant cell is surrounded by a solution with a high concentration of sucrose, then the cell will decrease in volume and mass. In this experiment, chunks of potato were placed inside 6 different solutions, each varying in concentration of sucrose. The potato chunk placed in water with 0 molars of sucrose added began with a volume of 2.025mm3, and increased to a volume of 2.268mm3 overnight. This was an increase in volume by 12%. This potato chunk began with a mass of 2.1 grams and increased to

To reach equilibrium, hypotonic solutions will move towards hypertonic solutions so that there will be an even concentration of solutes between the two solutions. When a potato cylinder is placed in a solution that is hypotonic (has a lower concentration of solutes than it), water in the hypotonic solution will move toward the more hypertonic potato. However, solutions that have a higher concentration of solutes (hypertonic) than the potato, will force water out of the potato. Therefore, if a potato

The data collected from this experiment demonstrates that the potato undergoes a hypotonic change when exposed to water as well as a hypertonic change when saturated in a sucrose solution. Throughout the experiment, each piece of potato was introduced to a different concentration of a sucrose and water solution. The sucrose solution, due to its density, did not enter the potato cells while the water was easily diffused into the cells through pores in their membranes. Water undergoes osmosis in situations

relation, potato cores were placed in different solutions with varying levels of sucrose and water. The common conception was that the increase in sucrose within a solution will cause osmosis to occur to a lesser extent between the potato and the solution. To measure this, the potatoes were weighted after a night of soaking in the solutions to test for a change in weight. It was the general conception that the greater the amount of sucrose within the solution, the lighter the potato will be. To test
