osmoticly

Osmoticly is an adverb that would describe something done by or relating to osmosis. In standard usage, the preferred forms are osmotically or by osmosis. Osmoticly appears infrequently and is often considered a nonstandard or misspelled variant, so it is generally avoided in formal writing.

Osmosis is the passive movement of a solvent, typically water, across a semipermeable membrane from a region of lower solute concentration to higher solute concentration. The driving force is the osmotic pressure created by solute differences on the two sides of the membrane. Water moves to dilute the side with higher solute concentration, until equilibrium is reached or opposing forces balance the system. Cells rely on osmosis to regulate volume and turgor pressure.

Confounding terms include osmolarity and osmolality, which quantify solute concentration, and osmotic pressure, which measures the tendency of water to move across the membrane. Osmotic processes differ from simple diffusion because they involve a barrier that is selectively permeable to the solvent rather than to solutes. When describing phenomena osmotically, one explains how solute concentrations influence water movement across membranes.

Practical contexts include biology, medicine, and agriculture. For example, red blood cells undergo swelling (hemolysis) in hypotonic solutions and shrink (crenation) in hypertonic solutions. In clinical settings, intravenous fluids are classified as isotonic, hypotonic, or hypertonic based on their osmolarity relative to blood plasma, reflecting osmotic principles that would be described as osmoticly active or relevant in everyday language.
