Structure-breaking and

Aqueous solutions of non-electrolytes, especially of non-polar solutes, may show the reverse effect and increase the proportions of ice-like components. The non-polar part of organic electrolytes such as soaps and wetting agents may predominate in increasing the ice component. Thus solutes can be divided into two classes structure making and structure breaking, and in some metal-finishing process solutions both types of solute may be added. 

The order of cations and anions regarding these structure breaking and making properties is related to their position in the lyotropic or Hofmeister series, such as... 

The change in the ion hydration energy between the bulk and the water-air interface for structure-making ions is so large compared to kT, that these ions practically do not approach the interface. The change is not so steep when a solid interface is immersed in water, particularly when the surface has sites which can bound structure-making ions. In what follows, it will be assumed that the anions are structure breaking and hence interact with the surface via an attractive potential of the type (Wx >0, see Fig. 3a) ... 

Notwithstanding the considerations of Section 2.12.1, the use of the bulk dielectric constant of water for dilute solutions of nonelectrolyte is not very inaccurate in the region outside the primary solvation sheath. The point is that in this region (i.e., at distances > 500 to 1000 pm from the ion s center), there is neghgible structure breaking and therefore a neghgible decrease in dielectric constant from the bulk value. 

The complexities discussed with respect to also apply to structure-breaking and structure-making effects compete to provide a variety of sign combinations and a range of magnitudes for S . 

The second endothermic process (region B) is observed at the temperature higher 230 °C and ends at 270 °C. And during this process crystalline structure breaks and polyester melts. This transition, as crystallization, is phase. High temperature of PETP melting is described by specific role of aromatic nucleus linked by p - para-position [245].
