This study aims to analyze the conception, threshold concept, and troublesome knowledge in chemical reaction topic. This study uses qualitative methods, document analyses, as well as interviews with chemistry teachers to obtain information about threshold concepts and troublesome knowledge. From the results of the analysis of several journals obtained that there were still many misconceptions encountered when students study chemical reactions. While the results of the interview, threshol concept in chemical reaction consisted of mixtures, physical and chemical properties, material changes, concepts of protons and electrons, electron configurations, chemical bonds, intermolecular forces, attractive forces between charges, compound nomenclatures, chemical formulas, and Lavoisier’s laws. While troublesome knowledge includes complexity of particles involved, complexity of interactions that may occur, complexity of applying Lavoisier’s Law, and language used.
