Thermoanalytical studies of reactions involving basic zinc salts were made as an example of application of thermal analysis to the fundamental research on developing teaching materials for chemistry education. The studies were complemented by pH titrimetry, thermometric titrimetry, chemical analysis, IR spectrometry, and X-ray diffractometry. On the basis of the results, the possibility was suggested that some investigative teaching materials are developed by introducing the precipitation reactions and thermal decomposition of the basic zinc salts into chemistry courses at a secondary education level. It was proposed that the thermoanalytical measurements for the basic zinc salts applied in the present study are also utilized successfully as teaching materials for educating thermal analysis at universities and colleges.
