Surface tensions
With so many fish stocks under pressure, increasing catch levels for one population by 30 per cent might appear catastrophic. But European fishing ministers believe such a move might help tackle two problems. Fishermen in the North Sea will be able to catch more cod this year, but cod fisheries elsewhere around Europe will be further restricted. EU ministers agreed late last month the fish quot...
متن کاملOn the Surface Tensions of Binary Mixtures
For binary mixtures with fixed concentrations of the species, various relationships between the surface tensions and the concentrations are briefly reviewed.
متن کاملSurface and interfacial tensions of hofmeister electrolytes.
We present a theory that is able to account quantitatively for the surface and interfacial tensions of different electrolyte solutions. It is found that near the interface, ions can be separated into two classes: the kosmotropes and the chaotropes. While the kosmotropes remain hydrated near the interface and are repelled from it, the chaotropes loose their hydration sheath and become adsorbed t...
متن کاملSurface tensions and surface potentials of acid solutions
A theory is presented which allows us to quantitatively calculate the excess surface tension of acid solutions. The H, in the form of hydronium ion, is found to be strongly adsorbed to the solution-air interface. To account for the electrostatic potential difference measured experimentally, it is necessary to assume that the hydronium ion is oriented with its hydrogens pointing into the bulk wa...
