Question 9 1 pts There is a solution in the arms of a U-tube, separated at the bottom by a selectively permeable membrane. The membrane is permeable to sodium chloride (salt), but not to glucose (sugar). Side A is filled with a solution of 0.4 M glucose and 0.5 M of sodium chloride. Side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Compare the tonicity – Side A is to Side B. SIDE...

1) Two aqueous solutions are placed in a U tube (one on each side) separated by a semipermeable membrane. One solution is one liter of 0.05 M urea (a molecular solute) and the other is one liter of 0.02 M Na2SO4. Assume ideal solutions at the same temperature. i) Which solution has the higher osmotic pressure? ii) In order to stop water from flowing, pressure must be applied to which side of the tube? A) i) urea, ii) urea B)...

In many biological solutions, water is the solvent, meaning that solute molecules are dissolved in it (think of salt or sugar water). If a solute does not move across a semipermeable membrane, it is асr known an osmotically active solute. For the following examples, assume that the solute is osmotically active. In osmosis, water molecules move across the cellular membrane down the gradient (from an area of low solute/high water concentration to an...
