Open Question
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?
