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.
