Analytical chemistry and qualitative-quantitative analysis practices have an important place in chemistry education. Operations such as experimental steps in volumetric analysis, reactions, and determining the amount of matter require problem-solving and higher-order thinking skills due to mathematical calculations. Students have difficulty and anxiety in making calculations in the volumetric analysis. This research aimed to examine the ability of chemistry teacher candidates to use the data obtained from the neutralization titration experiments in the calculation of the experimental result and to analyze the effects of information obtained from experiments on solving volumetric analysis problems. The sample of the study consisted of 13 chemistry teacher candidates studying in the chemistry teaching program of a state university. The research employed a descriptive survey model. Experiment data sheets and question solutions were taken as written answers. As a result of the research, it is noteworthy that the teacher candidates have problems in calculating the results of the experiment, and this has been overcome with increasing applications.

“…Difficulties in solving problems in chemistry subjects such as stoichiometry arise from problems in conceptual understanding (Chandrasegaran, Treagust, Waldrip, & Chandrasegaran, 2009). Students should pay attention to conceptual understanding while studying and learning chemistry, and teachers should pay attention to conceptual understanding when teaching chemistry (Derman, Kayacan, & Kocak, 2016).…”

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.
