Osmolarity and tonicity are related but distinct concepts. Thus, the terms ending in -osmotic (isosmotic, hyperosmotic, hyposmotic) are not synonymous with the terms ending in -tonic (isotonic, hypertonic, hypotonic). The terms are related in that they both compare the solute concentrations of two solutions separated by a membrane. The terms are different because osmolarity takes into account the total concentration of penetrating solutes and non-penetrating … Web9 aug. 2024 · Osmolarity is defined as the total concentration of particles in body liquids and is expressed as the number of solute osmoles (the number of particles that are osmotically active) per litre of solution (Osm/L). The osmolarity of body fluids needs to be maintained within very narrow values.
