Question

Work in groups of 3. Add 5 mL of 0.1% solution to tube 1, 5 mL of 0.9% NaCl solution to tube 2, and 5 mL of 10% NaCl solution to tube 3. Into each tube, add 3 drops of red blood cell solution. Shake gently and observe which solutions become pink/clear indicating complete hemolysis (C), and which stayed opaque/red to indicate partial and zero hemolysis (P or N, respectively). Record in data table 5. Mount 1 drop of the initial blood cells, and the final solutions from tubes 1, 5 and 10 on individual glass slides. Add a coverslip to each and observe at 400X. Draw and describe the shapes of the red blood cells that you can observe: Specify whether the solutions in tubes 1, 5 and 10 each contain solutions that are hypotonic, hypertonic, or isotonic. What is the NaCl concentration of blood, based on your results?

Explanation / Answer

Answer:

As we know Hypo = Less, Hyper = More, Iso = Same

20)

21) The NaCl concentration of blood according to the result is the Tube which has an isotonic solution that is of 0.9% NaCl concentration.
