Conductometric titration is a type of titration that measures the change in electrical conductivity during a chemical reaction. It is based on the principle that the conductivity of a solution is directly proportional to the concentration of ions present in the solution. By measuring the conductivity at different stages of a titration, we can determine the equivalence point and the concentration of the analyte.
The type of titration that can be effectively conducted using conductometric titration is the titration of strong acids with strong bases. This is because strong acids and strong bases dissociate completely in solution, producing a high concentration of ions. The high concentration of ions leads to a significant change in conductivity during the titration, making it easily detectable.
Here's why conductometric titration is effective for this type of titration:
1. High conductivity difference: Strong acids and strong bases produce a high concentration of ions in solution, resulting in a large change in conductivity during the titration. This makes it easier to detect the equivalence point and accurately determine the concentration of the analyte.
2. Sharp equivalence point: The titration of strong acids with strong bases generally exhibits a sharp equivalence point, where the pH of the solution changes rapidly. This sharp change in pH corresponds to a significant change in conductivity, allowing for precise detection of the equivalence point.
3. No interference from other ions: In the case of strong acid-strong base titrations, there are no additional ions present in the solution that could interfere with the conductivity measurement. This ensures that the observed change in conductivity is solely due to the reaction between the acid and base.
4. Wide range of conductivity: Conductometric titration can measure a wide range of conductivity values, allowing for the detection of both strong acids and strong bases. It can accurately measure both low and high concentrations of ions in solution.
Overall, conductometric titration is particularly suitable for the titration of strong acids with strong bases due to the high conductivity difference, sharp equivalence point, absence of interference, and wide range of conductivity that can be measured.

Conductometric titration is particularly effective for titrating strong acids with strong bases, where the change in conductivity is sharp and easily detectable. While it can be used in other types of titrations, it is most commonly associated with acid-base titrations.
