Which statement accurately reflects the coulometric titration of chloride?

In coulometric titration, a constant current is passed through the solution, which is essential for this type of titration process. This method involves generating titrant (in this case, silver ions) in situ at the generator electrode via electrolysis. The application of a constant current allows for the precise and controlled generation of a known amount of titrant, correlating directly with the amount of chloride present in the sample.

The presence of a constant current is crucial because it ensures that the electrochemical reaction occurs at a consistent rate, allowing for a reliable and accurate determination of chloride concentration as the generation of titrant occurs steadily. By maintaining this constant current, analysts can monitor the resulting change in the potential as chloride reacts with the silver ions produced.

The other statements might relate to concepts within electrochemistry or titration processes but do not accurately describe the essential characteristic of coulometric titration specific to chloride detection.
