Homework Answers
Ans-a- in this case the beaker containing 7% salt solution is hypertonic for the bag containing 5% salt solution. So water will move from low solute (hypotonic) to high solute concentration (hypertonic) by osmosis. Its mean water will move from bag to the beaker.
Ans-b- due to the movement of water from bag to beaker, the solute concentration in beaker decrease while the solute concentration in bag will increase. At a point when there would be 6% salt solution in both beaker and bag the equilibrium is reached and net movement of water will get stop.

Post-Lab Questions For each of the tubing pieces, identify whether the solution inside was hypotonic, hypertonic, or isotonic in comparison to the beaker solution in which it was placed. Which tubing increased the most in volume? Explain why this happened.

5 A cell s a semipermeable membrane through which water may pass. If a cell, having a salinity (salt content) of 1.5% w/v NaCl, is placed in a solution made of normal physiological saline (0.9% w/vNaCl) which way will the water flow? Explain your answer.
