Determination of Chloride ion concentration by titration. Titration is a method used to determine the concentration of an unknown substance in a solution by adding measured amounts of a standard solution that reacts with the unknown substance. Precipitation titrations involve reactions that produce insoluble compounds, with silver nitrate being a commonly used reagent. Potassium chromate can be used as an indicator for the endpoint of argentometric titrations, forming a red precipitate with silver ions. The determination of chloride ion concentration in a solution through titration with silver nitrate as a titrant is a common analytical technique known as Mohr’s method. By carefully adding silver nitrate to the solution containing chloride is formed, signaling the endpoint of the titration. This method is commonly used in various industries and laboratories to accurate measure chloride ion concentrations. In the practical, Mohr’s method was used to determine the concentration of the chloride ion concentration in a solution through titration with the silver nitrate.

Titration is a widely used method in analytical chemistry for determining the concentration of an unknown substance in a solution. One common application of titration is the determination of chloride ion concentration using Mohr's method. This technique involves the titration of a chloride-containing solution with silver nitrate as the titrant, with potassium chromate serving as an indicator for the endpoint of the reaction. The formation of a red precipitate signals the completion of the titration, allowing for the accurate measurement of chloride ion concentration. This method is crucial in various industries and laboratories for quality control and research purposes. In this study, we performed a practical demonstration of Mohr's method to determine the chloride ion concentration in a solution through silver nitrate titration.
