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.
