What are the advantage and disadvantage of conductometric titration?
Advantages and Disadvantages of Conductometric Titration This process is very useful in the titrations of very dilute solutions and weak acids. The end-point of this method of titration is very sharp and accurate when compared to a few other titration processes.
What are the advantages of conductometric titration over visual titration?
Conductometric titration can be used with very diluted solutions and weak acids. It gives more accurate end-point. Conductometric titration can be used with colored or turbid solutions in which end point can not be seen by naked eye. Conductometric titration can be used where there is no suitable indicator.
What are the applications of Conductometry?
APPLICATION OF CONDUCTOMETRY :- Determination of solubility and Ksp of sparingly soluble compound. Determination of mode of ionization of complex compound. Conductometric titration & precipitation titrations. Purity of water.
What is the principle of conductometric titrations?
The principle of conductometric titration is based on the fact that during the titration, one of the ions is replaced by the other and invariably these two ions differ in the ionic con- ductivity with the result that conductivity of the solution varies during the course of titration.
What is the difference between conductometric titration and normal titration?
The key difference between potentiometric and conductometric titrations is that potentiometric titrations measure the potential across the analyte, whereas conductometric titrations measure the electrolytic conductivity of the analyte. From this titrant, we can determine the concentration of an unknown solution.
What are the advantages of volumetric analysis?
The advantages of volumetric analysis are fast and accurate result, simple apparatus and different methods for different kind of substances. When titrate react with titrant, the process called as titration. Here titrate means substance to be analyzed and titrant means reagent of know concentration.
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 the meaning of Conductometry?
Definition of conductometry : determination of the quantity of a material (as an element or salt) present in a mixture by measurement of its effect on the electrical conductivity of the mixture.
What do you meant by Conductometry?
Which cell is used in Conductometry?
The two electrode cell is the most commonly used conductivity cell Glass cells have electrodes made of platinum….Conductivity Cells.

What is conductometric titration simple?
Definition: The process of determining the quantity of a sample by adding measured increments of a titrant until the end-point is reached. The titration is monitored by measuring the conductance of the solution.
Which is better conductometric titration or potentiometric 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 …
What are the disadvantages of conductometric titration?
The disadvantages of conductometric titrations are mentioned as follows. High concentration is not possible to measure with this method. A Solution is required to be diluted for measurement. Less accurate than other methods. Changes in salt level enhanced conductivity in the solution mask. Less satisfactory than other methods.
What is equivalence point In conductometric titration?
Equivalence Point – The point in conductometric titration at which conductivity undergoes a sudden change. Principle of Conductometric Titration Conductometric titration is based on the measurement of conductance of the solution. The conductance of the solution (analyte + titrant) depends on following three factors –
What is the best method for titration of colored solutions?
Conductometric titration can be used with colored solutions where endpoint can’t be seen and can be used where there is no suitable indicator. No indicators are required and therefore, a colored solution can be conveniently titrated.
How do you titrate a reaction mixture for conductivity?
Conductometric titration is done by monitoring the electrolytic conductivity of a given reaction mixture while one reactant is constantly added to it. The theory of this type of titration states that the end-point consequent to the titration procedure can be indomitable by means of conductivity measurement.
