Strong acid in water, Chemistry textbook, Chemistry teacher, Degree of ionization
In this research, the textbook contents related to the ionization degree of strong acid in water were analyzed from 1945 year syllabus to chemistry II textbook in 2009 revised curriculum. Fifty chemistry teachers' cognition related to the species of strong acid in water, and the relationship between the degree of ionization was surveyed by a questionnaire and interviews. As results, most of the teachers thought the species of strong acid in water based on the degree of ionization represented on the chemistry II textbooks. They didn’t recognize the conflict of the degree of ionization and definition of strong acid on the textbooks, and then they awakened the conflict, they could not solve the problem.
