采用两次不同体积的硫酸铜溶液与锌粉反应，测量出反应后温度上升的数值，根据两者的差值对结果进行校正，计算出反应热。实验装置采用在磁力搅拌器上以塑料杯作为反应器，测定只需３～５ｈ，测定的误差小于１％。实验装置简单、容易掌握、测定时间短、准确度高。 Two different volumes of copper sulfate solution were reacted with zinc powder to measure the temperature rise after the reaction, and the result was corrected according to the difference between the two to calculate the heat of reaction. Experimental equipment used in the magnetic stirrer plastic cup as a reactor, measured only 3 ~ 5h, the measured error of less than 1%. Experimental device is simple, easy to grasp, measurement time is short, high accuracy.
