WebThis titration, measured using a pH meter (potentiometric titration), allows us to identify chemical properties of the acid such as the molecular weight and pK a because the … 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…
WebpH CUT OFF/STAT – in pH cut off mode the end point is determined in a pre-selectable pH window. In pH-STAT mode the pH value is maintained until the pre-selected time interval is reached.
