Exercise 2 20 1. What is the osmotic pressure of a 0.300 M solution of glucose in water at 37'C (310 K)? Compared to a solution with an osmotic pressure of 5.00 atm, is the 0.300 M glucose solution isotonic, hypotonic, or hypertonic at this temperature? 2. What is the osmotic pressure of the hot water in a mineral bath that is 1.35 M in various ions and has a temperature of 40C? If you soak in this hot mineral bath for an hour, will you lose or gain water, or will there be no effect? Remember, the osmotic pressure of the fluids in body tissue is around 7.7 atm. 3. When a small cucumber is soaked in brine (concentrated NaCl in water), it shrivels up to form a pickle. Explain what is happening here in terms of osmosis.
