【摘要】 建立了一套用于电解质溶液电导测量的交流平衡电桥。当被测阻值在100～11000Ω范围内时,其测量相对误差不超过0.05%。为检验该装置的可信度,作者对NaCl、KCl水溶液及甲醇溶液的电导进行了测量,实验值与文献值吻合较好,表明该装置具有良好的测试精度。更多还原

【Abstract】 In this paper,a set of AC bridge for measuring the conductance of electrolyte solution has been constructed. When the resistance measured is between 100 and 11000 ohms,the relative error is less than 0. 05 per cent. In order to test the reliability of the instrument,the measurement of the conductance of sodium and potassium chlorides has been carried out in aqueous and methanol solutions at 298. 15K. The experimental results are in good agreement with literature data,which shows that the instrument has an excellent precision and good accuracy.更多还原
