碳酸钠的制备与分析实验条件的优化
|
摘要
对《无机及分析化学实验》教材中"碳酸钠的制备与分析"实验所存在的问题进行了探索研究,通过对比工艺的安全性、实验用时的长短、产品的产率及产品质量,给出了实验室利用碳酸氢铵和粗盐制备碳酸钠的安全可靠的方案,改进了产品的分析方法双指示剂法.
The problems existing in the experiment of " Preparation and Analysis of Sodium Carbonate" in inorganic and analytical chemistry experimental textbooks were explored and studied. By comparing the safety of the process,the length of the experiment time,the yield of the product and the quality of the product,a safe and reliable scheme for preparing sodium carbonate from ammonium bicarbonate and crude salt in the laboratory was given,and the double indicator method for product analysis was improved.
