To assess the major sources of students' difficulties in qualitative analysis (QA), 51 grade 10 students (15 to 17 year old) from three secondary schools were interviewed. The results found that the major sources of students' difficulties in understanding QA are formation of precipitates, formation of complex salts and addition of acid.
