一、前言当进行化学反应时,由于能量的变化,常常伴随着放热或吸热现象。而且温度的变化与作用物质的量、具有一定的关系。测温滴定是以测量反应体系的温度变化为基础的容量分析方法。以待测溶液中加入滴定剂的量与对应的温度变化作图,根据等当点附近滴定曲线的显著转折来判断滴定终点。最初应用的测温滴定方法是:滴定反应在 I. Introduction When conducting chemical reactions, due to changes in energy, often accompanied by exothermic or endothermic phenomenon. And the temperature changes and the amount of material, has a certain relationship. Thermometric titration is a capacity analysis method based on measuring the temperature change of a reaction system. The amount of titrant added to the solution to be measured is plotted against the corresponding temperature change and the titration endpoint is judged based on the significant transition of the titration curve near the equivalence point. The initial temperature titration method is: titration reaction in
