Abstract
Movement of ions in the solution behavior, since ancient times both in the chemical industry or the biosphere, all people want to understand the issues. We use the electric field to drive ion movement, but if we supply the DC field , we may make the charge accumulation near the electrode, that may cause our uncertainty of our measure environment. Therefore, we will change for the AC current electric field, in order to avoid charge accumulation of the issue, hoping to make the measurement environment not to change over time. Applied electric field according to testing by the ionic current, we derive a model to explain the ion movement in the exchange of electric field behavior and the theoretical value will make a comparison with the experimental results and found quite close to the trend curve.
In our model derivation, we have found a coulomb force between ions that will change with increasing concentration, this force will attract positive and negative ions together, we hope to use this to explain, when the high concentration to a degree, the solution will be the crystallization phenomenon.
And we hope that with the use of physical point of view, to explain the movement of ions in the solution behavior, in explaining the process of simulation parameters, we can find, have greater mass of the ions, the smaller the scattering rate; smaller mass ion, scattering rate is larger, this finding can be interpreted in the chemical industry, the use of hydration to the concept to explain the equivalent ions in the water quality changes, and size of the ions in the water can feel a different resistance.
