Observation Before Immersion After 15 minutes of Immersion Starch solution in the cellophane Iodine in the beaker Table 4.1.b Reaction of Starch to lodine Solution Starch in Iodine Solution Table 4.2. Osmosis Solutions Test Tube 1: 0.9% NaCl (Isotonic) Observe Shape of Red Blood Cells Drawing Test Tube 2: Distilled Water (Нурotonic) Test Tube 3: 3% NaCl (Hypertonic) Conclusion
Soft contact lenses are made from hydrogels, which make them soft and flexible. It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.
A 150mM NaCl solution is isotonic to the red blood cells, causing no net movement of water into or out of the cells. Predict what would happen to the red blood cells in the following environments: 100 mM NaCl 300 mM NaCl 50 mM NaCl 0 mM (distilled water)
A cell with a total of 0.3 osmol/L is placed into a solution with a total of 0.2 osmol/L. It is assumed that the osmotic particles cannot pass through the cell membrane. Answer the following true or false questions. 1. All particles will diffuse down a concentration gradient, that is, move from a high concentration into a lower concentration 2. Diffusion down a gradient happens because particles are constantly moving (Kinetic Theory) 3. When solvent particles move down a gradient through a membrane it is called osmosis
In the experiment showing osmosis through a semipermeable membrane, 3 corn syrup mixtures are used. If equal volumes of two solutions (10% corn syrup and 30% corn syrup) were placed in two beakers that were separated by a semipermeable membrane, permeable only to water, and let sit for 1 hour, what would be the expected concentration/s of the two solutions at the end of the time period? Explain using solute concentration, water concentration etc.
Solutions with a lower concentration of solutes than the concentration inside the cell are hypotonic. True False
A cell with a total of 0.2 osmol/L is placed into a solution with a total of 0.3 osmol/L (switched from the previous question). It is assumed that the osmotic particles cannot pass through the cell membrane. Answer the following true or false questions. 1. Solvent is more concentrated in the cell 2. Water will osmose out of the cell 3. The cell will shrink and may look crenated 4. Plant cells have a cell wall to protect them from dehydration caused by osmosis
A cell with a total of 0.3 osmol/L is placed into a solution with a total of 0.2 osmol/L. It is assumed that the osmotic particles cannot pass through the cell membrane.
