氢氧化物(包括含氧酸)的酸碱性是无机化合物最基本的性质之一,论述甚多,但在定量或半定量方面,就整个周期系(包括主副族)而言,还缺乏较全面、统一的讨论。本文从离子极化理论出发,提出可用正离子的水合场强度作为统一的衡量依据,不仅可用作周期 The acid-basic properties of hydroxides (including oxoacids) are one of the most basic properties of inorganic compounds and are extensively discussed, but in terms of quantitative or semi-quantitative aspects, they are lacking in terms of the entire cycle (including the main subgroups) More comprehensive and unified discussion. Based on the theory of ion polarization, this paper proposes that the hydration field strength of positive ions can be used as a uniform basis of measurement, not only as a period
