In analytical chemistry, potentiometric titration is a technique similar to direct titration of a redox reaction. It is a useful means of characterizing an acid. No indicator is used; instead the electric potential is measured across the analyte, typically an electrolyte solution. To do this, two electrodes are used, an indicator electrode (the glass electrode and metal ion indicator electrode) and a referenc… WebThe purpose of this experiment is to perform a potentiometric titration of an acid using a glass electrode and a pH meter. The potential that develops across the glass membrane … strong bluetooth receiver
