Absolutely. Everything is permeable in everything else. What permeation rates are you wanting to see?For any liquid and any gas? Probably not.(snip)
Mass transport always proceeds from regions of high chemical potential for a species to regions of low chemical potential; it ceases when activities of all species are equal on both sides of the "membrane." Differences in permeation rates for various species allow the opportunity to run "horse races" and achieve separations of mixtures/solutions; run the the race long enough and every horse crosses the finish line.(snip) But what about pressure.. would gas diffuse if on another side is liquid with slightly higher pressure? (like water does)
Well what I was trying to say that you can't possibly (in my mind) create something that's essentially permeable to any and every liquid and essentially impermeable to every gas. Or vice versa.Absolutely. Everything is permeable in everything else. What permeation rates are you wanting to see?
Are you insane?permeation rate - the higher the better
The gas really doesn't matter as long as its not He or H. It would be good that its colored gas. My first thought was Cl2 made at home from electrolysis of NaCl dissolved in H2O.
