Abstract
The article addresses the problem of preparing school students for the experimental round of chemistry Olympiads using the example of qualitative analysis of unknown substances. The relevance of the study is обусловлена тем, что despite relatively high performance in the theoretical round, students experience significant difficulties when completing experimental tasks. The paper demonstrates the need to develop a systematic methodological guide aimed not only at mastering individual qualitative reactions but also at fostering critical thinking, practical skills, and the ability to independently plan experiments, which are essential for successfully completing Olympiad tasks. The aim of the study is to provide a theoretical justification, develop, and test methodological recommendations for preparing students for the experimental round of chemistry Olympiads.
