Re: dielectric constant of water



Pentcho Valev wrote:

In my view, the effect is due to the so-called clathrate water which is
formed in the vicinity of hydrophobic surfaces (in this case the surface of
the wall of the bag) and is sometimes called "water of hydrophobic
hydration". When the wall is thin, there is polarization, i.e. "water of
polar hydration" is formed near the surface and you measure a high
dielectric constant. However if the wall is thick, water of hydrophobic
hydration predominates - it forms many layers with almost no polarization.


Since the bag is on both sides of the water, wouldn't the polarization
effects simply cancel (same sign - no net field)?
