Discussion The experiment tested Ovis aries RBC tonicity in varying concentrated solutions. As more solutes occupied the solutions, each solution became increasingly hyperosmotic in comparison to the RBC’s. The hypothesis of this experiment was that, if the red blood cells are placed in contact with NaCl solution, then the degree of hemolysis of the red blood cells should be greater, due to the movement of water by osmosis. Figures 1 and 2 in the results section demonstrates; as the NaC...
