摘要
电导法是测定弱电解质平衡常数多种方法中的一种,它具有实验过程简单、实验结果准确等特点。本文用电导法测定了醋酸在298K的离解平衡常数,实验值为1.70×10-5,与理论值1.75×10-5接近。
Electric conductivity method is coe of the means which can be used to determine the ionization equilibrium constant d electrolyte solution. The experimental process is simple, experimental results are accurate by using the method of the electric conductivity. The ionization equilibrium constant of CH3OOH at 298K is determined in this paper. Experimental value of ionization equilibrium constant of CH3OOH is 1.70 × 10^-5, which approaches to the theoretical value, 1.75 × 10^-5.
