摘要
对碳酸氢钠溶液中微粒浓度作了定性分析,发现了碳酸氢钠溶液浓度的3个临界点,预测溶液中微粒浓度大小顺序。通过定量计算求得碳酸氢钠3个临界点的溶液浓度,3个临界点将碳酸氢钠溶液浓度分成4个范围,得出在每个浓度范围内相应的微粒浓度大小顺序。
This paper qualitatively analyzed particulate concentrations in sodium bicarbonate solution,three critical points were found and the order of particulate concentration was predicted.The particulate concentrations at three critical points were defined by quantitative analysis.The whole concentration range was divided into four parts by three critical points,and the particulate concentrations were ranked in every range.
