摘　　要：溶解热测定实验是大学物理化学实验课程中的经典实验,通常选用KNO_(3)作为溶质,但KNO_(3)的管理流程复杂,不方便大批量使用,综合管理成本高,选用了常见的几种化学试剂作为溶质,通过对比实验现象、实验结论重复性、实验过程可操作性等方面得出:NH_(4)Cl均优于其他试剂,因此推荐NH_(4)Cl作为教学用实验试剂。The dissolution heat measurement experiment is a classic experiment in the physical chemistry experiment course of universities.KNO_(3) is usually used as the solute,but the management process of KNO_(3) is complex,inconvenient for large-scale use,and the management cost is high.This article selects several common chemical reagents as solutes.Through comparing experimental phenomena,experimental conclusion repeatability,and experimental process operability,it is concluded that NH_(4)Cl is superior to other reagents.Therefore,NH_(4)Cl is recommended as the experimental reagent for teaching.
