许多常见的实验系统都有含有弱电解质的双层电，包括带缓冲的系统。扩散层边界处的pH值是决定体系物理化学状态的重要参数，包括表面电荷密度。我们证明了玻尔兹曼平衡关系可以作为弱电解质双电层的精确解。利用这些结果，我们提供了缓冲双电层中最大pH变化的封闭形式关系，即边界电位。重要的是，我们的结果表明，为强电解质开发的平衡双电层概念可以扩展到包括弱电解质。
Many common experimental systems have electric double layers containing weak electrolytes, including systems with buffers. The pH at the boundary of the diffuse layer is an important parameter for determining the physicochemical state of the system, including surface charge density. We show that the Boltzmann equilibrium relation can be used as an exact solution for weak electrolyte electric double layers. Using these results, we provide a closed-form relation for the maximum pH change in a buffered electric double layer, in terms of the boundary potential. Importantly, our results suggest that equilibrium electric double layer concepts developed for strong electrolytes can be expanded to include weak electrolytes.
