Question

Learning Goal: To learn about osmosis and about isotonic solutions, hypertonic solutions, and hypotonic solutions. Osmosis is the net movement of water across a semipermeable membrane from an area of lower concentration to an area of higher concentration. Part A: A semipermeable membrane is placed between the following solutions. Which solution will decrease in volume? Solution A: 1.81% (m) starch The water will continue to move across the semipermeable membrane as the system attempts to reach equilibrium, where both solutions have the same concentration. Solution B: 6.89% (m/v) starch There are three different ways a solution can be described in relation to a cell placed in the solution: isotonic, hypotonic, and hypertonic. Compared to the cell, an isotonic solution exerts the same osmotic pressure as the cellular fluids. In other words, it... Part B: A semipermeable membrane is placed between the following solutions. Which solution will increase in volume? Solution C: 7.40% NaCl Solution D: 14.6% NaCl Part C: A red blood cell has been placed into each of three different solutions. One solution is isotonic to the cell, one is hypotonic to the cell, and one solution is hypertonic to the cell. Sort each beaker into the appropriate bin based on the cell's reaction in each solution:
