Question
b. What if the solute concentration outside in the beaker was greater than the solute concentration inside the osmometer? What would happen to water movement? Explain. 4. Suppose you put the same salt solution into two osmometers and place both osmometers in beakers of distilled water. You keep one osmometer setup at room temperature and put the other in a cold room at 10 C. Would you observe any differences between the two osmometers? Explain. You are a physician and are treating a patient (Robert) with cholera (a bacterial intestinal infection). Robert has severe diarrhea and dehydration and, if untreated, will die in a matter of hours. Robert MUST receive fluids. Would you give Robert an intravenous infusion of distilled H20, a hypotonic salt solution, an isotonic salt solution, or a hypertonic salt solution? Choose one and explain your choice. 5. Use your results from tubes #6 and #7 in Part F to explain the following statement: An iso-osmotic solution may not be isotonic. 7. Explain this statement: An iso-tonic solution is always iso-osmotic but an iso-osmotic solution is NOT always isotonic. 8.Explanation / Answer
4. When we put osmometers in distilled water then water enters the osmometer. This happens due to osmosis. When a cell is kept in a hypertonic solution it will shrink. If we keep a cell in a hypotonic solution it will swell. Now water will enter the osmometers but as they are kept at different temperatures. One is placed at room temperature and one is placed at 10 degrees. Then the one having a higher temperature will have faster movement of water in it rather than the one at 10 degrees. As temperature influences the rate of movement of particles.
5. I will give a hypotonic solution in an intravenous injection. If a hypotonic solution is injected then the water will enter the cells and they will get hydrated again.
If we keep a cell in a hypotonic solution it swells due to osmosis. As water moves from its higher concentration to lower concentration.
