Osmosis and its solvents...
« on: August 03, 2005, 08:02:48 AM »
We all know Osmosis refers to movement of SOLVENT across a partially permeable membrane.
Other than water, what other solvent are there which are able to move through a partially permeable membrane?

osmosis is usually the application of membranes with spaces big enough for solvent molecules. as long u have a solvent whose molecules are smaller or roughly the same size as water, it'll do.

those membranes are called semipermeable :)

i would think it would be membrane-specific, although osmosis refers to water particularly. membranes,after-all, are somewhat molecular filters. when the molecules that diffuse through the membranes are not water molecules, the correct term is diffusion.

osmosis occurs with a semipemreable membrane. When the membrane is permeable to all molecules diffusion will occur. So osmosis will occur depending on the membrane that is used.

Solvent are not limited to liquids.  For example, nitrogen production uses compressed air (and a variety of other processes) to selectively pass air through a semipermeable membrane to product Nitrogen gas.  This can also be applied to other gasses.
