Methon Permiability Test:
((1)) There are 2 bottles(150 ml.). One is filled with 10 M Methanol and other is filled with same amount of water (80 ml.)
((2)) As we put those two connected bottles into a water bath (where the temperature is 80oC), the water passes to the Methanol side through the membrane and doesnot come back even the temperature goes down to room temperature.
((3))This is called the back-diffusivity. But, what is the exact mechanism behind this. Could anyone here expalin for me, please?

It's all about concentration gradient. The water is trying to create an equal concentration of methanol on both sides, so the water travels to the methanol side in an attempt to diffuse the methanol and thus, lower its concentration.
