9. Solutions

A solution with the same osmotic pressure as the blood is

A semipermeable membrane is placed between the following solutions.

Which solution will increase in volume?

Four U tubes each have distilled water in the right arm, a solution in the left arm, and a semipermeable membrane between the arms. If the solute is LiF, which solution is most concentrated?

Identify the direction of water flow between 2 solutions separates by semipermeable membrane, where are the solute particles.

If the fluid surrounding a patient's red blood cells is depleted in electrolytes, is crenation or hemolysis more likely to occur?

A red blood cell placed in pure water will swell because:

Assume that two liquids are separated by a semipermeable membrane, with pure solvent on the right side and a solution of a solute on the left side. Make a drawing that shows the situation after equilibrium is reached.

Indicate the compartment (A or B) that will increase in volume for each of the following pairs of solutions separated by a semipermeable membrane:

Are the following solutions isotonic, hypotonic, or hypertonic compared with a red blood cell?

c. 0.9% (m/v) NaCl

What does it mean when we say that a 0.15 M NaCl solution is isotonic with blood, whereas distilled water is hypotonic?

A pickle is made by soaking a cucumber in brine, a salt-water solution. What makes the smooth cucumber become wrinkled like a prune?

A semipermeable membrane separates two compartments, A and B. If the levels in A and B are equal initially, select the diagram that illustrates the final levels in a to d:

a. 0.9% (m/v) NaCl solution

Look up the composition of Ringer's solution used in the treatment of burns and wounds.

b. What is the osmolarity of the solution? Is it hypertonic, isotonic, or hypotonic with blood plasma (0.30 osmol)? Discuss possible medicinal reasons for the osmolarity of the solution.

Research information related to dialysis and answer the following questions:
