An analysis of high school science textbook contents and pre-service teachers' perceptions related to sulfuric acid

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 SO₄^2-. 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.
