osmosis criteria

[biofreak]

if a u-tube contains absolute alcohol in its 1 limb and pure water in its other limb , both separated by a semi-permeable membrane, then will osmosis occur between the two?(absolute alcohol contains no water molecules)

[SkepticLance]

Depends on the membrane. If its pore size is such that water molecules can pass through, but not alcohol, then there will be osmosis from water to alcohol side.

[Moh]

it probably will as water molecules pass through a semi permeable mebrane, therefore resulting in the high water concentration moving to the alcohol side.
