ADVANTAGES AND DISADVANTAGES OF CONDUCTOMETRY IN CHEMISTRY

Conductometry: Let us discuss advantages and disadvantages of Conductometry. This method is also called as conductometric titration method. Types, mobility, concentration of ions and temperature affects the electrochemical conductivity

Some of the advantages of conductometry are as follows:

  1. In this method as coductance  is measured by conductivity meter , indicator is not required.
  2. Conductometric titration works for coloured solution.
  3. Accurate results can be obtained by conductometry.
  4. It is suitable for both weak base as well as weak acid.
  5. This method is also suitable for turbid solution.

Some of the disadvantages of conductometry are as follows:

  1. Sometimes the salt level increases in the solution which masks the conductivity and do not gives accurate result.
  2. Sometimes high concentration of ions masks the conductivity and hence do not give accurate results.

Applications of Conductometry

Some applications of conductometry are discussed here, conductometry in analytical chemistry is used to measure the progress of chemical reactions. Conductometric titration is carried out in order to measure the  electrical conductivity of the reaction mixture. This type of titration gives a sharp end point for the colored solution.

  • This type of titration is used to check water pollution in lakes as well as rivers.
  • It is also used to check the alkalinity of the fresh water
  • Salinity of the sea water can also be checked by this method.
  • It is also used to trace antibiotics.
  • Used for tracing microorganism in food microbiology
  • To check the solubility of sparingly soluble salts.
  • Purity of distilled water and de ionised water can determined.
