摘要
针对常用的电导法测定酸碱反应速率常数过程中,数据处理比较繁琐的弊端,提出用酸度计测定酸碱反应溶液的pH值,进而求反应速率常数的方法。实验证明:求出的反应速率常数k值稳定,数据处理简单。用计算机作一维线性拟合图,计算结果及线性关系均比较理想。
In order to solve the problem in the measurement of rate constant for acid-base reaction by conductivity instrument, acidometer has been employed to determine the rate constant according to the measured pH values. The experiment results show that the calculated rate constant is very steady and in consistent with the experiment data.
