Abstract It is difficult to measure the dissolution heat of solution with unclear thermal effects through calorimetry experiments. This paper uses conductivity sensors to measure the conductivity data of electrolyte suspensions as a function of temperature,and obtains the relationship between temperature and solubility product constant,and uses Van't Hoff equation to calculate the dissolution heat of electrolytes. To cultivate students' ability to solve difficult chemical problems through innovative experimental methods,and improve the guidance effect of chemical theory on learning practice.
