classify the effect of following solution on a red blood cell as causing crenation, hemolysis or no effect. 0.5% (m/v) NaCl aqueous solution.
The computed amount of Sodium and Chloride ions in the blood is less than 0.4% (m/v) for both ions. Since the prepared NaCl solution has a concentration of 0.5% (m/v) it is now considered as a hypertonic solution. When the red blood cells are exposed in a higher salt solution environment, the cells will release water so as to balance the concentration inside and outside the cells. Therefore red blood cells will undergo crenation. This means that the cell will shrink due to the loss of water inside the cell. Eventually the cell will die since water is an essential compound to maintain the cellular function processes.
