Conductometric titration is based on the principle that the ionic conductivity of a solution changes as different ions are introduced through the titration process. Conductivity is related to the number of free ions in the solution, and this number changes as the titrant is added. Therefore, the correct answer is option C.

`The primary principle underlying conductometric titration is the change in ionic conductivity of the solution.`
Conductometric titration is a type of titration that relies on measuring the electrical conductivity of a solution during a titration process. Here's how the change in ionic conductivity of the solution serves as the primary principle underlying conductometric titration:
- `Principle of Conductivity:`
- When ions are present in a solution, they can conduct electricity. The conductivity of a solution is directly related to the concentration of ions in the solution. As the concentration of ions changes during a titration, the conductivity of the solution also changes.
- `Titration Process:`
- During a conductometric titration, a titrant is added to a sample solution containing the analyte. The titrant reacts with the analyte to form a product. As the reaction progresses, the concentration of ions in the solution changes, leading to a change in the solution's conductivity.
- `Endpoint Detection:`
- The endpoint of a conductometric titration is determined by monitoring the change in conductivity of the solution. Initially, the conductivity will be high due to the presence of ions from both the analyte and titrant. As the titrant reacts with the analyte and forms a product, the conductivity of the solution will decrease. The endpoint is reached when there is no further change in conductivity, indicating that the reaction is complete.
By utilizing the change in ionic conductivity of the solution, conductometric titration allows for precise endpoint detection and accurate determination of the concentration of the analyte in the sample solution.
