Question:
How does the size of blood cells change when placed in an aqueous solution containing more than 0.9% (mass/volume) sodium chloride?
How does the size of blood cells change when placed in an aqueous solution containing more than 0.9% (mass/volume) sodium chloride?
Show Hint
- Hypertonic solution: Water leaves the cell, causing shrinkage.
- Hypotonic solution: Water enters the cell, causing swelling.

Solution and Explanation
Blood cells shrink.
Step 1: Understanding Hypertonic Solutions A solution with more than 0.9% NaCl is hypertonic compared to the fluid inside blood cells.
Step 2: Effect on Blood Cells Due to osmosis, water moves out of the blood cells into the hypertonic solution to balance the concentration gradient. This leads to shrinking (crenation) of blood cells.
