Which will be an appropriate hypothesis for the experiment? (salt) and an egual amount of water as the cell. In this case the water moves equallyOsmosis is the process where water moves across a selectively permeable cell membraneThe term isotonic describes a solution which has an equal concentration of soluteThe term hypotonic describes a solution which has less solute (salt) and morewater, The process of osmosis must be tightly controlled by çells, otherwise they will die.with proteins and salts dissolved in it, preventing the unnecessary gain of water by ourby diffusion. Water moves from the solution with more water to the solution with lessFor example, if you place a red blood cell in pure (distilled) water, it will quickly take upinside the cells and the plant can no longer support itself against the pull of gravity.The term hypertonic describes a solution which has more solute (salt) and lesssolvent (water) than the cell. In this case the cell will lose water.In plants, osmosis is just as important, Plants with too little water will wilt. This happenswater until it bursts. That is why plaşma, the liquid portion of our blood is made of waterwhen water moves out of the cells by osmosis, Without this water there is little pressureHowever, atter watering the plant, the cells become re-inflated with water and the plantstands upright. The effect of water loss on plant cells is shown in the diagram below.9/28/21Osmosis ExperimentBackgroundblood cells.solvent (water) than the cell In this case the cell will gain waterinto and out of the ell.H2OH.OH20CABFigure 1A. Plant cell placed in pure water. This cell will become inflated because the water outsidethe cell is at a higher concentration than the water inside the cell. As water moves in byosmosis the vacuole fills up and presses out against the cell wall.B. Plant cell in salt solution equal to the concentration inside the cell, This cell has nooverall gain or loss of water because whatever moves out will be replaced by water movingin.47 C. Plant cell placed in a salt solution greater than the concentration inside the cell. Thiscell will lose water as the water moves by diffusion from higher to lower concentration.In this lab activity you will observe the effects of osmosis on plant cells. You will use theweight of cubes of potato to see how much water moves in and out of cells in differentsalt solutions.

Consider two solutions at a certain temperature. Solution X has a nonelectrolyte as a solute and an osmotic pressure of 1.8 atm. Solution Y also has a nonelectrolyte as a solute and an osmotic pressure of 4.2 atm. What is the osmotic pressure of a solution made up of equal volumes of solutions X and Y at the same temperature? Assume that the volumes are additive.
Plants that thrive in salt water must have internal solutions (inside the plant cells) that are isotonic with (have the same osmotic pressure as) the surrounding solution. A leaf of a saltwater plant is able to thrive in an aqueous salt solution (at 25C) that has a freezing point equal to 0.62lC. You would like to use this information to calculate the osmotic pressure of the solution in the cell. a. In order to use the freezing-point depression to calculate osmotic pressure, what assumption must you make (in addition to ideal behavior of the solutions, which we will assume)? b. Under what conditions is the assumption (in part a) reasonable? c. Solve for the osmotic pressure (at 25C) of the solution in the plant cell. d. The plant leaf is placed in an aqueous salt solution (at 25C) that has a boiling point of l02.0C. What will happen to the plant cells in the leaf?
In terms of Raoults law, distinguish between an ideal liquid-liquid solution and a nonideal liquid-liquid solution. lf a solution is ideal, what is true about Hsoln, T for the solution formation, and the interactive forces within the pure solute and pure solvent as compared to the interactive forces within the solution? Give an example of an ideal solution. Answer the previous two questions for solutions that exhibit either negative or positive deviations from Raoults law.

A gaseous solute dissolves in water. The solution process has H=15 kJ. Its solubility at 22C and 6.00 atm is 0.0300 M. Would you expect the solubility to be greater or less at (a) 22C and 1 atm? (a) 18C and 6 atm? (a) 15C and 10 atm? (a) 35C and 3 atm?
Erythrocytes are red blood cells containing hemoglobin. In a saline solution they shrivel when the salt concentration is high and swell when the salt concentration is low. In a 25C aqueous solution of NaCl, whose freezing point is 0.406C, erythrocytes neither swell nor shrink. If we want to calculate the osmotic pressure of the solution inside the erythrocytes under these conditions, what do we need to assume? Why? Estimate how good (or poor) of an assumption this is. Make this assumption and calculate the osmotic pressure of the solution inside the erythrocytes.
