WebIn 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 osmotic flux. WebSince impermeable sodium ions are the major osmoles in an extracellular fluid, tonicity is effectively equal to the osmolality of all body cells. Unlike osmolarity or osmolality, tonicity does not have any units. It is calculated by the formula: Fluid Tonicity = 2 × sodium level of plasma Depending on their tonicity, solutions are of three types:
