讨论给出的实验证据过充电，也被称为电荷反转。这种现象很普遍。最普遍的解释是特定的化学吸附。然而，过度充电也可以根据离子-离子相关性来解释，这是一种物理类型的解释，也可以是特定的。为此，人们提出了几种理论。因此，对于同一个观测结果，存在着两种可供选择的解释的奢侈问题。本文的目的是批判性地考虑各种方法，并试图设计实验选项来区分这两种解释。
A discussion is given of the experimental evidence for overcharging, also known as charge reversal. The phenomenon is very common. The most general explanation is specific chemical adsorption. However, overcharging can also be explained on the basis of ion-ion correlations, which is rather a physical type of interpretation, and which can also be specific. Several theories have been developed for that. So, there is the luxury problem that two alternative explanations are available for the same observation. The purpose of this paper is to consider the various approaches critically and try to devise experimental options to discriminate between the two interpretations.
