重量法和滴定法相结合的综合性设计实验:硫酸钡中钡含量测定

Comprehensive Design Experiment of Determining Barium Content in BaSO4by Gravimetric Method and Titration Method

在BaSO_4沉淀重量法测可溶性钡盐中钡含量的常规实验基础上,设计了一个重量分析法和滴定分析法相结合的综合性实验,并且通过误差计算评价2类分析方法,赋予这个实验更宽广的内涵和应用性。

Based on the conventional experiments of BaSO4 precipitation gravimetric method to determine barium content in the soluble barium salt, this paper designed a comprehensive experiment combining gravimetric method and titration analysis method, and evaluated two kinds of analysis methods by error calculation, which could give the experiment wider connotation and application.
