The Study of Grade 11th Students’ Preconceptions about Neutralization Reaction
Keywords:
Student’s Conception, Alternative Conception, Acid-Base, Neutralization ReactionAbstract
The purpose of this study was to study thirty Grade 11th students’ pre conceptions about Neutralization reaction in a large school under the University in Bangkok. The research instrument was two-tier and open-ended concept survey about acid-base reactions. The data were analyzed by categorizing into groups. The result found that most students (66.67%) chose the correct answer. However, some of them (16.67%) hole alternative conceptions by identifying the products neutralization reaction. For example, A neutral reaction is the acid-base reaction in which the product is salt and water. Following concept of properties of substances derived from neutralization reaction, most students (23.33%) explained that the products are neutral properties. For example, it is neutral because it is from strong acid + strong base with similar strength. While 16.67% explained that it is neutral because acid and base neutralized each other. For example, it will be mixed together and the pH will be cleared by one another, which may neutralize the pH.
