Order increases with distance
Large and weak, small ions may be embedded in the pores of the water structure lattice. no
The same kind of ions have different effects on water structure. "Structure temperature" -
The temperature of pure water with the same structural degree as the water in the ionic solution at 25 ℃
- Used to describe this difference. The order of ions to reduce the structural temperature (to enhance the structure of water) is: Mg □＞ H □＞ Ca □; OH□＞F□。 The ionic order of increasing the structure temperature (weakening the structure of water) is: K □ ＞ Rb □ ＞ Cs □; ClO□＞NO□＞Cl□。 Obviously, it is difficult to explain the above phenomenon only by the charge density of ions, and there is no perfect answer so far.
