摘　　要：测定了磷酸氢二钾和磷酸二氢钾不同摩尔比的混合溶液在不同温度下的电导率。研究结果表明:在固定磷酸氢二钾和磷酸二氢钾摩尔比的情况下,其混合溶液的电导率随温度的升高而升高,而在同一温度下混合溶液的电导率随磷酸氢二钾和磷酸二氢钾摩尔比的增加而增加,最后趋向于平稳。The electric conductivities of the mixed solution with different molar ratio of dipotassium hydrogen phosphate and potassium dihydrogen phosphate are determined under the different temperatures. The results show that the electric conductivity rises with the increasing temperatures, under the same molar ratio of potassium phosphate mixed solution; the electric conductivity rises with the increasing molar ratio of potassium phosphate mixed solution, under the same temperatures and the tend becomes stable finally.
