A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. Solution A: 3.13 % (m/v) NaCl Solution B: 3.87 % (m/v) glucose Solution C: distilled H2O Solution D: 6.63 % (m/v) glucose Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl Drag each solution to the appropriate bin.

Step 1
9% (m/v) NaCl or 300 mOsm/L. Now, let's analyze each solution: Solution A: 3.13% (m/v) NaCl This solution has a higher concentration of solute than the normal osmolarity of blood, so it is hypertonic. When a red blood cell is placed in a hypertonic solution, Show more…

A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. Solution A: 2.97% (m/v) NaCl Solution B: 2.03% (m/v) glucose Solution C: distilled H2O Solution D: 23% (n/v) glucose Solution E: 0% (m/v) glucose and 0.9% (m/v) NaCl Drag each solution to the appropriate bin.

Properties of Solutions
A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis. To prevent crenation or hemolysis, a cell must be placed in an isotonic solution such as 0.9% (m/v) NaCl or 5.0% (m/v) glucose. This does not mean that a cell has a 5.0% (m/v) glucose concentration; it just means that 5.0% (m/v) glucose will exert the same osmotic pressure as the solution inside the cell, which contains several different solutes. A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. Solution A: 3.21% (m/v) NaCl Solution B: 1.65% (m/v) glucose Solution C: distilled H2O Solution D: 6.97% (m/v) glucose Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl Drag each solution to the appropriate bin.
