Answer:
Explanation:
Potentiometric titration belongs to chemical techniques of investigation in which the endpoint of the titration is monitored with an indicator electrode that records the variation of the potential as a function of the amount (usually the volume) of the added titrant of exactly known concentration. Potentiometric titrations are mainly resourceful because of indicator electrodes suitable for the reading of almost every chemical reaction used in titrimetric reactions.
Moreover, potentiometric titration is used for measuring the change in the electrical potential when a neutralizing agent (titrant) is added to a chemical solution. Besides, it is a volumetric method in which the potential between two electrodes is measured (referent and indicator electrode) as a function of the added reagent volume. ... The part of the curve that has the maximum change marks the equivalence point of the titration.
Advantages of potentiometric titration
Potentiometric titrations are based on standard electrode potential change observed through a potentiometer.
Potentiometric titration measures the change in electrical potential as a neutralizing agent (titrant) is added to a chemical solution.
Moreover, this process is much accurate, inexpensive for making chemical analyses and more useful for measuring acid concentration.
Several compounds, especially in pharmaceuticals, require high purity. To check for sample (analytic) purity, you must perform titration so that one volume of the solution reacts the same as another solution.
The process also measures oxidation or corrosion against the amount of titrant added, making it suitable for measuring acid concentration. The process uses a minimal amount of substance, making it an inexpensive method. The automotive, pharmaceutical, food, beverage and environmental companies are examples of industries using Potentiometric titrations.
The main advantage of using Potentiometric titration method is that it is an inexpensive method. It uses small quantities of substances.
