AbstractWith theadvancementofeducational informatization，highschoolchemistryexperimental teaching faces the need for innovation.This paper focuses on theapplication ofdigital experiments inthe teaching of highschoolchemistry reaction principles，conducting a practical study exemplified bythe determination of neutralization reaction heat.It expounds on the advantages of digital technology in experimental teaching，such as real-time monitoring，visual representation，andhighprecision.Thepaperalsodetailsdigitalpracticestrategies，includingtheadaptationofexperimental instruments and reagents， pre-experiment preparations， operation specifications，data processing，and teaching interactions.The study shows that digital experiments effectively enhance the efectiveness of experimental teaching， assist students inunderstandingabstractchemicalconcepts，andcultivate theirscientific inquiryandanalyticalabilities， providing new paths and methods for the reform of high school chemistry experimental teaching.
