    both sides) Red blood cells are bound by a membrane which allows water to pass through while generally restricting the solutes. This process, called osmosis, causes cells to shrink due to loss of water when placed in hypertonic solution. On the other hand, red blood cells absorb water (called endosmosis)...

    The range of concentrations was adequate but I would possibly create more concentrations if I repeated the experiment so that I would have more varied results, i.e. 0.10M, 0.50M, 1.0M, and so on. This way would have allowed me to also find out the isotonic point far more accurately as the one that I...
