Isotonic, Hypotonic, and Hypertonic Solutions
Describe each of the following solutions as isotonic, hypotonic, or hypertonic. Indicate whether a red blood cell placed in each solution will undergo hemolysis, crenation, or no change.
a. a 5% (m/v) glucose solution
b. a 0.2% (m/v) NaCl solution
a. A 5% (m/v) glucose solution is isotonic. A red blood cell will not undergo any change.
b. A 0.2% (m/v) NaCl solution is hypotonic. A red blood cell will undergo hemolysis.
