摘要
碳酸氢钠晶体的制备以侯氏制碱法为背景,涉及溶液纯化、减压过滤、结晶等多步操作,是一项经典的无机化学实验。本文分析了实验操作方法对产品纯度和收率的影响,并提出了一些指导性建议。本科生可以借鉴本文提供的信息,精心完善个人实验的操作,提高动手实践能力和分析问题能力。
The preparations of sodium bicarbonate crystalloid are against a backdrop of Hou＇s process for soda production. It involves several operations including heating solution, purifying and decompression filtration, which is a classic inorganic chemistry experiment. This thesis analyzes the impact of the exper imental method of operation on the experimental results and purity and puts forward some guidance suggestions. Undergraduate students can learn from the information provided in the paper and carefully improve the personal experimental operation. Their hands on skills and ability to analyze problems have im- proved greatly.
