Abstract

Problem-solving is an important skill in analytical chemistry. This study aims to determine how chemistry teacher candidates use volumetric analysis problems and reveal the errors made. The research employs a descriptive survey model. The sample of the study consists of seven chemistry teacher candidates studying in the chemistry teaching programme. Questions requiring comparing the volume spent in NaOH and HNO3, H2SO4, and H3PO4 titrations were asked within the scope of the study. The solution to the problem and explanations were recorded in a video. The results show that there are problems in determining the volume of NaOH. Many students wrote the titration reactions correctly, but there were problems with the effect values. It is noteworthy that those who made mistakes did not understand the first step of the problem. The students can prevent such mistakes with the help of a diagram summarizing the steps to be followed in the titration process.
