Assay by Potentiometric Titration in Pharmaceutical …

WebIn 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. WebIn potentiometry we measure the potential of an electrochemical cell under static conditions. Because no current—or only a negligible current—flows through the electrochemical cell, its composition remains unchanged. For this reason, potentiometry … Note. Many controlled-potential coulometric methods for Cu 2 + use a potential that … newest version of word for mac

The pH of the solution in the flask varies with added NaOH, as shown in Figure 1 a. The pH changes quite slowly at the start of the titration, and almost all the increase in pH takes place in the immediate vicinity of the endpoint. interrupted while snapshotting table
