Explain what happens on both sides of the semi-permeable membrane. In
hydrostatic conditions, a relation exists between pressure variation and height
variation in the capillary tube:
AP=p.g.Ah
Where
AP is the change in pressure or difference in pressure between two sides
p is the density of the liquid
Where
g is the standard gravity (9.8 m/s²)
Ah is the change in height or difference in height between two sides
Determine the relation between the osmotic pressure and the concentration of
solute. Compare your results with the Morse's equation given below. This law is
valid for an ideal solution with a low concentration of solute.
