难溶化合物的溶度积测定是无机化学实验和普通化学实验的基本内容之一,国内大多数教材均安排和设计了该内容的实验.其中,碘酸铜是用于测定得较多的一种难溶物.实验中,基于沉淀饱和溶液中的铜离子与氨水生成颜色更深的铜氨配离子,用比色法来测其浓度,进而求知碘酸铜的溶度积.但是,上述方法由于近似成份较多、学生对标准色阶的颜色
Solubility determination of insoluble compounds is one of the basic contents of inorganic chemistry experiments and general chemistry experiments, most of the domestic teaching materials are arranged and designed experiments for the content of which, copper iodate is used to determine a more In the experiment, based on the precipitation of saturated solution of copper ions and ammonia to produce darker color of cuprammonium with colorimetric method to measure its concentration, and then find the solubility of copper iodate product. However, the above method Due to the approximate composition of more students in the standard color level of color
