Question

Osmotic Pressure: In an osmotic pressure demonstration, a glass column and submerged into a beaker of pure water. The me through but not solute molecules. Over time, the fluid rises up a semi-permeable membrane that contains sugar water is connected to mbrane allows water molecules to pass the column. This process is called osmosis. e up the column? (Think about the rate of water flow in both directions.) 11. Eventually, the liquid stops rising. Why? (Something is opposing the flow of water). 12. At the start of the demonstration, we could have prevented the liquid from rising at all? How? The osmotic pressure of a solution is operationally defined as the pressure that must be exerted on the surface of the solution to prevent osmosis. 13. What would happen if even more pressure were applied? (This is called reverse osmosis and is commonly used to purify sea water!) 14. Two solutions with the same osmotic pressure (same concentration of solutes) are said to be isotonic. must intravenous fluids be isotonic with your blood? Osmotic pressure is a colligative property of a solution. That is, its magnitude depends on the concentra dissolved particles but does not depend on the nature of the dissolved particles. Interestingly, osmotic p (TT) can be calculated using an equation that is very similar to the ideal gas equation:

Explanation / Answer

Ans 10 :

The liquid rises up in the column because the water travels from high concentration gradient to a lower concentration gradient , the process which is known as osmosis. The sugar solution has lower concentration of water , so the water flows and its height rises in the glass column.
