摘要
采用计算机图解法,以副反应系数为主变数,应用Excel电子表格和Origin作图程序进行计算、作图,可以极为简便地确定在掩蔽剂存在下,微溶物开始沉淀时和完全沉淀时的pH值,图形直观明了,具有确定的物理意义.
By calculating with Excel and ploting with Origin and by making side reaction coefficient as major function, in the presence of masking agents, the pH values at the beginning of and after the full precipitation of slightly soluble substance, are determined and confirmed simply. The graph, which has specific physical meaning, can be understood easily.
