摘    要:根据强酸弱碱盐的水解原理并通过系列对比实验,找出配制常见极易水解盐SbCl3,B1(N03)3,Hg(N03)2,Hg2(N03)2,FeCl3,Fe(N03)3和Fe2(SO4)3所需相应酸量最少并且又不产生水解.可避免因酸量过大而引起使用过程中出现的反常现象.该法与文献所加入相应酸量比较,均有不同程度的节约,具有应用推广价值.

关 键 词:无机盐水溶液  强酸弱碱盐  水解盐  配制方法  水解反应  酸根  碱根  结合能力  酸量

Abstract:Based on the hydrolytic principle of strong acidic and weak alkaline salts and through a series of check experiments, the minimum amount of acid for water solution of some highly solvable inorganic salts was found, such amount will not result in hydrolysis. This can prevent some abnormal phenomena that may occur because of the excessive use of acid. Compared with the amount of acid in the reference, the amount proposed in this paper is less, resulting in the economic use of acid, and the method is worth to be extensively used.
Keywords:Prepare  Water Solvable Salt  Acid
