| Abstract: | The temperature to remove the crystal water in copper sulfate pentahydrate was determined by the differential thermal analysis, and enthalpy change during the dehydration was studied. The results show that, when the heating rate is 10K/min, the dehydration process of copper sulfate pentahydrate is divided into three steps; compared with literature values, errors of calculated enthalpies of the three steps areT.67%, 6.60%, 5.42%. |
