Abstract

This article presents an easy and economical micro-scale alternative for the generation and identification of five inorganic gases (chlorine, ammonia, sulphur dioxide, carbon dioxide and nitrogen dioxide), and reflection regarding their use in the classroom. It aims to minimize the dangers and difficulties involved in obtaining gases and their identification. The experiments were performed using plastic Petri dishes, which where pre-drilled in the centre of the lid, where a plastic pipette was inserted for deliver the reagent solution. The proposed work has been used with two groups of high school and college students. In both cases, its implementation has been evaluated positively.
