溶解度平衡通常在普通化学课程中被介绍，但对真实溶液的非理想行为的提及很少。在重量学背景下的定性分析化学课程中引入了非理想行为。通常，这一概念只是一种学术练习，没有实验应用。本文报道的溶度积常数的测定与其他实验的不同之处在于，非理想性是通过德拜-休克尔理论考虑的，只做了很少的简化假设。
Solubility equilibria are usually introduced in the general chemistry course with limited mention of the nonideal behavior of real solutions. Nonideal behavior is introduced in the qualitative analytical chemistry course in the context of gravimetry. Often this concept is left as an academic exercise with no experimental application. The determination of a solubility product constant as reported here differs from other experiments in that nonideality is taken into account through Debye-Huckel theory by making few simplifying assumptions.
