A thistle funnel is filled wvith sucrose solution and kent inyerted in a beaker containin
A demonstration of osmosis.
(a) Water will diffuse across the membrane (as shown by arrows)
to raise the level of the solution in the funnel
(b) Pressure can be applied (as showvn) to stop the water movement into tie
OSMOTIC PRESSURE
yO.P. of solution is equal to that external pressure, which required to be appied on
solution in order to prevent osmosis or entry of water in it when the hypotonic ana
solutions are separated by a semipermeable membrane."
he osmOtic pressure of pure water is zero. O.P. is due to presence of solute into the so
The osmotic pressure of a solution is directly proportional to the concentration of sSolute t.
