Ions Concept

The concept of the ion is a continuation of the continuous substances by the effects of Debye falkennegan wylen and alex, who lives on the circumstances. E = 10 ^ 5 v / cm. In this accretion is the result of the conductivity was observed (effect of Warren). In this accretion conductivity results from the fact that limited time (time off) is a form of pressure. Something about the atmosphere to form ions. In fact high, very fast exchange with the resulting loss at atmospheric pressure. Atmosphere did not have time to form and also can not slow down the ions. The result of this asymmetry is not visible and the conductivity are increase. For the same reason the addition of conductivity at high frequencies around 3 x 10 ^ 6 cms (dybye effects) / falkennegan. The transition ions on the instructions that it should have a very difficult motion at atmospheric pressure that can not be measured and will follow the movements of atoms are very difficult at atmospheric pressure and an increase conciliates. At high frequencies of both could be asymmetrical electropothic no results.

Molar conductivity of electrolyte, does not depend on the concentration of K appropriate if compared with the concentration of electrolytes. However, in practice, the molar conductivity berparsial against concentration. One reason is the number of ions in solution may not contain or proportional to the concentration of electrolytes. For example, the concentration of ions in weak acid solution depends on the acid concentration is complicated, and alloys that make up the concentration of the acid. Do not make double the existing number of ions. Both because the ions interact more strongly. Then the conductivity can not be proportional to the number of ions available. Measurement of the concentration dependence of molar conductivity showed the existence of two classes of electrolytes. General properties of the molar conductivity of electrolyte strength is only slightly decreases with increasing concentration. General properties of a weak electrolyte solution is a tool of the normal conductivity when the concentration approached or declined sharply to low values when the concentration increases. This classification depends on the solute and solvent used, for example lithium chloride which is a strong electrolyte in water. Strong electrolyte is a substance that perfect ionized in solution and includes ions.
