Water And Osmosis

Water always diffuses toward the solution that has the higher solute concentration. This is because solutions with a lot of solute contain fewer molecules than a solution with less solute. The solute concentration inside a red blood cell is equal to a 0.9% solution of sodium chloride (NaCl). When water enters the cell it enters by osmosis and diffuses in and causes the cells to burst. This is because water is a hypotonic solution. It has a lower solute concentration than the cell. When 1.5% NaCl solution is added to the blood cell it cause water to diffuse out and leave the cell and move toward the higher solution and make the cell shrivel. When 0.9% NaCl was added to the blood cell there was no change because that is what the body keeps it
