化学“101计划”合成化学实验课程建设——过二硫酸钾的制备和鉴定
摘要:
基于化学“101计划”合成化学实验课程建设目标，设计并实施了以电化学合成方法为核心的综合性实验——过二硫酸钾的制备与鉴定。实验通过电解饱和硫酸氢钾溶液合成目标产物，结合化学滴定与X射线衍射技术进行纯度分析和结构表征，构建了“合成-分析-表征”一体化的教学流程。该教学设计不仅使学生掌握电化学合成的基本原理与实验技能，而且理解无机合成、物理化学、仪器分析等多学科知识的交叉与融合。通过计算电流效率、分析产物纯度与结晶度，有效培养学生的处理数据能力、批判性思维和解决复杂问题的科研素养。本实验内容综合、设计严谨，高度契合“101计划”对提升学生创新能力和实践能力的深层目标，为培养新时代高素质化学人才提供了有力支撑。

Chemistry “101 Plan” synthetic chemistry experiment course construction: study on the preparation and identification of potassium persulfate
Abstract:
Based on the construction objectives of the synthetic chemistry laboratory course under the Chemistry “101 Plan”, a comprehensive experiment centered on electrochemical synthesis methods, namely the preparation and identification of potassium persulfate, was designed and implemented. The experiment involves preparing the target product through low-temperature electrolysis of a saturated potassium bisulfate solution. It integrates chemical titration and X-ray diffraction (XRD) techniques to form a complete “synthesis-analysis-characterization” workflow. This design enables students to master fundamental principles and practical skills in electrochemical synthesis while understanding the integration of multidisciplinary knowledge, including inorganic synthesis and instrumental analysis. Through calculating current efficiency and analyzing product purity and crystallinity, the experiment effectively cultivates students’ abilities in data processing and critical thinking. This practice-oriented project aligns with the objectives of “101 Plan”, providing strong support for developing high-quality talents with innovation capabilities and scientific research proficiency.
