碘酸铜溶度积的测定是“无机化学实验”试用教材中的一个实验。该实验使用无机实验的普通仪器,来测定物理化学常数,对提高一年级学生的实验水平大有帮助。但按照该教材所提供的方法,测得的K_(sp)值(10~(-5))比文献值(10~(-7))高出两个数量级。文献对此作了改进,大大减少了实验准备的工作量,测得的K_(sp)值也与文献值接近。我们在文献
Determination of copper iodate solubility product is an experiment in “Inorganic Chemistry Experiment” teaching materials. This experiment uses a common instrument of inorganic experiments to determine the physicochemical constants, which will greatly help to improve the experimental level of the first grade students. However, the K_ (sp) value (10 ~ (-5)) was two orders of magnitude higher than the literature value (10 ~ (-7)) according to the method provided in this textbook. The literature has improved this, greatly reducing the workload of the experimental preparation, the measured value of K_ (sp) is also close to the literature value. We are in the literature
