Isotonic solutions have the same concentration of solutes as red blood cells. A 0.9% NaCl solution, also known as saline, is isotonic to red blood cells and used in medical settings for intravenous fluid replacement. Distilled water is hypotonic (lower solute concentration) and can cause red blood cells to swell and burst. A 0.9% glucose solution is hypertonic (higher solute concentration) and can cause red blood cells to shrink. Alcohol is also hypotonic and can damage red blood cells.
