Determination of Chloride the Fajans method

1. Title

Determination of Chloride using the Fajans Method Chlorides are commonly found in various environments, including natural waters, industrial effluents, and biological systems. The determination of chloride ion concentration is crucial in numerous fields such as environmental monitoring, food quality control, and clinical diagnostics. Among the various analytical techniques available for chloride measurement, the Fajans method stands out for its simplicity, sensitivity, and effectiveness. This method employs a titration approach based on the principles of adsorption on an indicator-dye, allowing for precise endpoint determination. The Fajans method is particularly recognized for its application in the titration of halides with silver nitrate as the titrant. The key aspect of this method is the use of an adsorption indicator, typically fluorescein or dichlorofluorescein, which undergoes a color change when a specific concentration of silver ions is attained. During the titr
