电导法测定醋酸的电离平衡常数实验的改进
Experimental Improvements on Determination of Dissociation Constant of Acetic Acid by Conductometry
摘要
Abstract
Experimental improvements on determination of dissociation constant of acetic acid have been made by using thermostat, improving solution preparation, and changing the way of using electrode. These improvements greatly expand the lifetime of electrodes and reduce the amount of reagents, reducing the experimental cost. The experimental procedure is much simpler and results are more accurate. These improvements enhance the students′understanding about the principle and the method.关键词
