### Effect of Various Solutions on Red Blood Cells #### Question: If you placed a red blood cell (RBC) into the following solutions, identify what will happen to the RBC (will it go through crenation, hemolysis, or no change) and what type of solutions are the following (isotonic, hypotonic, or hypertonic): a. **0.2% m/v NaCl** b. **10% m/v Glucose** ### Explanation: - **a. 0.2% m/v NaCl** A red blood cell placed in a 0.2% m/v NaCl solution is likely to experience **hemolysis** because the solution is *hypotonic*. The NaCl concentration is lower than that of the cytoplasm of the RBCs, causing water to enter the cells, leading to swelling and eventual rupture. - **b. 10% m/v Glucose** A red blood cell placed in a 10% m/v Glucose solution is likely to undergo **crenation** because the solution is *hypertonic*. The concentration of glucose is much higher outside the cell than inside, causing water to move out of the cells, which results in the cells shrinking.
