What is potentiometric titration curve?
A potentiometric titration curve is a plot of potential as a function of the volume of added titrant. The curves have an “S” or backward “S” shape, where the end point of the titration corresponds to the inflection point.
What is potentiometric titration PDF?
Potentiometric titration is a laboratory method to determine the concentration of a given analyte. It is used in the characterization of acids. In this method, there is no use of a chemical indicator. Instead, the electric potential across the substance is measured.
What are potentiometric titrations explain in detail the potentiometric curves in acid base titration?
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 potential is measured across the analyte, typically an electrolyte solution.
What are the advantages of potentiometric titration?
The main advantage of using Potentiometric titration method is that it is an inexpensive method. It uses small quantities of substances. These kinds of titrations are more sharp and accurate as the equivalence point is not determined by using colored indicators.
What is the advantages of potentiometric titration?
Advantages of potentiometric titration: It is an economical titration method. It requires a small quantity of substances. There is no need to use indicators for potentiometric titration. The titrations results are accurate as no colour indicators are involved.
What is the importance of potentiometry?
Potentiometry is a technique that is used in analytical chemistry, usually to find the concentration of a solute in solution. In this technique, the potential between two electrodes is measured using a high-impedance voltmeter (Wang, 2000). Use of a high-impedance voltmeter ensures that current flow is negligible.
What is potentiometry used for?
Potentiometry, one type of electrometric method, is used to determine the concentration of a solute in solution. In potentiometric measurements, the potential between two electrodes is measured using a high impedance voltmeter.
