电导率仪法测定醋酸离解平衡常数

Detecting Dissociate Equilibrium Constant of Acetic Acid with Conductometer

根据在“电解质溶液的电导”实验中 ,用电导率仪测定醋酸的离解平衡常数获得成功的改革成果。阐述改用电导率仪测定电解质溶液的电导 ,既解决了常规实验教学中用交流电桥测定电导率所面临的仪器资源短缺的困难 ,满足了实验教学的需要 ,又用活了一批闲置的新仪器的实验开发经验。

On the basis of the successful measuring of dissociate equilibrium constant of acetic acid by using conductormeter in an experiment of “Conductance of Electrolyte Solution”, this paper discusses that the use of conductormeter to measure the conductivity of electrolyte solution can not only overcome the difficulty of scarcity of resource for the equipment used in the routine experiment teaching to measure conductivity but also make gook use of some idle instruments.
