hydrostatic pressure versus osmotic pressure

(one that permits only the solvent to pass through it), the direction of flow will be from the more dilute to the more concentrated solution (left to right in the illustration). This flow will continue until the hydrostatic pressure is developed at the concentrated solution fron..

Osmotic pressure is the pressure required to prevent the net movement of pure water into a solution so as to prevent the volume of the solution from increasi..

The pressure built up inside the cells as a result of the entry of water is called osmotic pressure. The entry of water into the cells is regulated by the solutes in the cell. Less concentration of solutes means more concentration of water. Positive osmotic h..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosi..

Vant Hoff, analyzing the available data on osmotic pressure of solutions concluded that osmotic pressure of dilute solutions varied with their concentration and temperature in the same way as pressure of the gas. He enunciated some laws for solution..

Diagram showing relationship of Osmotic Pressure (OP), Turgor Pressure (TP) and Wall Pressure (WP) The actual pressure exerted by the protoplasm of turgid cell against cell wall is the turgor pressure..

The positive osmotic pressure developed inside a cell as a result of entry of water is called turgor pressure. When the cells are full of water, they are called turgid and when they lose water, they are called flaccid. The root cells become turgid after the absorption ..

fig 3.5 As the values of P o A and P o B are constants at a particular temperature, it reveals that total pressure is a linear function of c B or c A i.e. the plot of P versus c A or P versus c B should be a straight line. The variation of P with mole fraction is given..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmotic pressure..

The osmosis process can actually be reversed if a pressure larger than the osmotic pressure be applied to the solution. This phenomenon has found uses in water purification, especially the desalination of sea wate..
