Definition and Principles of Osmotic Pressure Osmosisis the movement of water from low to high solute concentration that includes atoms, ions, or molecules dissolved in a liquid. The number of dissolved particles determines the rate of osmosis. The pressure created by water moving across a membrane...

Define osmotic pressure. osmotic pressure synonyms, osmotic pressure pronunciation, osmotic pressure translation, English dictionary definition of osmotic pressure. n. The pressure exerted by the flow of water through a semipermeable membrane separating
Osmotic pressure and its concept are very important in chemistry mainly in physical chemistry. If two solutions of having different concentrations and are separated by a semipermeable membrane, then an interesting osmosis process will happen. This articl

Osmotic pressure is expressed in terms of the change in the activity of the solvent a1 when a solute is present. According to the Gibbs-equation, the activity a1 is related to the mole fraction of the solute (notation here: 1-solvent, 2-solute). Since by definition the mole fraction is...
Osmosis is the transfer of solvent from a region of lower concentration to a region of higher concentration. Explore more about the definition of osmosis and osmotic pressure.
Osmotic pressure is that pressure needed to keep a solvent (no or low solute concentration) from passing across a semipermeable membrane into a solution containing dissolved solutes (high solute concentration). Being able to control the osmotic pressure is important to living cells, especially animal...
Thus, there is a completelymechanicaldefinition of the osmotic pressure, just as there is for the pressure in a molecular fluid. For an equilibrium suspension of colloidal particles subjected to thermal Brownian forces, this mechanical definition is shown to be exactly equal to the usual ''...
