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 ... WebSep 24, 2011 · A 0.9% solution (NS) is ISOtonic, a 0.45% solution (1/2 NS) is hyPOtonic, and 5% solution (D5) is hyPERtonic. Mixing D5 and 1/2 NS produces a solution that's 2.75% which itself is hyPERtonic. ...

WebA 5% dextrose solution in water (D5W) is isotonic in vitro, but the in vivo effect is that of pure water because the glucose is rapidly metabolized. Every infusion fluid should be isotonic (290+/-10 mosmol/kgH2O). Hypotonic solutions must move water from the extracellular space to the intracellular space.
