Conductometry titrations hand written notes pdf

Save (0)



Conductometry titration is a type of titration in which the electrical conductivity of the solution is measured during the titration. Conductivity is defined as the ability of a solution to conduct an electrical current. It depends on the charged particles present in the solution, such as ions and polar molecules.

In conductometry titration, the titrant is slowly added to the solution being titrated, and the change in electrical conductivity is measured. The conductivity changes as the concentration of the ions in the solution changes. The endpoint of the titration is determined by a sudden change in the conductivity, which indicates that all of the analyte has been reacted with the titrant.

This type of titration is commonly used for acidic or basic solutions, where the endpoint can be detected by a significant change in the pH of the solution. Conductometry titration is also used for redox reactions, where the transfer of electrons affects the conductivity of the solution.

The advantages of conductometry titration include its high sensitivity and precision, as well as its ability to determine the endpoint precisely. It is also a fast and straightforward method, requiring minimal sample preparation.

  1. However, conductometry titration requires a high degree of skill and accuracy in measurement, as well as careful calibration of the instrument. It is also limited to only certain types of reactions and cannot be used for non-conductive solutions.
