摘要
实验采用分光光度法测定PbI2的溶度积原理是用NaNO2将PbI2饱和溶液中的I-氧化成I2,测定其吸光度,并在标准曲线上查找出对应的I-浓度.计算出PbI2的溶度积常数为KSP=1.37×10-8,与文献值相比误差较小.
There have been several methods to measure the solubility product of PbI_2, but in college textbook of inorganic chemistry experiment only ion exchange resin method is adopted. We employ spectrophophotometric method to measure the solubility product of PbI_2. The result is ideal.
