Abstract

|
|
|
The purposes of this study were to analyze the contents of sulfuric acid in Science textbooks and Chemistry II textbooks, and to survey 10 pre-service teachers’ perceptions who majored chemistry education related to sulfuric acid. As results, most of the Science textbooks represented that sulfuric acid was divided into two H+and one SO42?. But this mistake might be corrected because sulfuric acid was divided into one H+and one HSO4?. Most of Chemistry II textbooks represented ionization steps of sulfuric acid, but same mistake was represented in some of Chemistry II textbooks. HSO4? is a weak acid, but some Chemistry II textbooks represented HSO4? as a strong acid. As results of the survey related to pre-service teachers’ perceptions, some pre-service teachers didn’t know the situation of particles in sulfuric acid solution, and they were affected on by the learning of high school classrooms.
