Accuracy of the end result is good. Electrolyte used in the reaction must be freshly prepared.
This titration can be performed even in the presence of a small amount of solute whose concentration is to be determined. Variation in electrolyte pH alters the result of titration.
What do we mean by potentiometric titration and give one advantage of it?
Potentiometric titration requires measuring the voltage change of a titration across a sample needing purification. It provides an adaptable, relatively affordable and highly accurate method to achieve high purity, essential to many fields, particularly pharmaceuticals.15 may 2018
What are the advantages of potentiometric titration over volumetric 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 meant by potentiometric titration?
Potentiometric titration belongs to chemical methods of analysis in which the endpoint of the titration is monitored with an indicator electrode that records the change of the potential as a function of the amount (usually the volume) of the added titrant of exactly known concentration.
What are different type of potentiometric titration?
There are four types of titration that fall under the category of potentiometric titration, namely acid-base titration, redox titration, complexometric titration, and precipitation titration.
What is the difference between direct potentiometry and potentiometric titration?
Compared to direct potentiometric measurements, potentiometric titrations generally offer increased accuracy and precision because potentials are used to detect rapid changes in activity that occurs at the equivalence point of the titration.25 sept 2014
Is potentiometric titration accurate?
Potentiometric titrations are direct titrations that require no indicator. In some models, however, two electrodes, an indicator and a reference electrode may exist. This kind of titration is far more accurate and precise than manual titration, with high accuracy up to three digits in milliliters.15 may 2018
Why potentiometric titration is better than conductometric titration?
When considering the difference between potentiometric and conductometric titrations based on the advantages, the potentiometric titrations do not need an indicator; it is far more accurate, and it can be automated, while the conductometric titrations can be suitable for coloured analytes and suspensions, and give ...18 jun 2019
