WebTonicity. In chemical biology, tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane. Tonicity depends on the relative concentration of selective membrane-impermeable solutes across a cell membrane which determine the direction and extent of ... WebApr 13, 2024 · Normal saline is a sterile solution that is isotonic, meaning it has the same concentration of dissolved particles as the body’s cells. It is a crystalloid fluid, so it can easily pass through the cell membrane, and is commonly used in clinical settings for fluid resuscitation, hydration, and to maintain fluid and electrolyte balance.
