摘要:We present in this paper a practical study in chemistry at secondary education level. It is an innovative task in the study of the photosensitive reaction Ag+ -->Ag. This experience presents three light sensitive reactions based on silver nitrate, but they have a different rate reaction. Moreover, this work researches the students’ ideas about chemical reactions in general, and photosensitive reactions in particular. Finally, this paper is about the educationals implications of this research.
