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.

Answer 1

Determination of chloride ion concentration by titration is a widely used method in analytical chemistry. This method involves adding measured amounts of a standard solution, such as silver nitrate, to a solution containing chloride ions. The endpoint of the titration is indicated by the formation of a precipitate, which signals the completion of the reaction. The use of potassium chromate as an indicator helps in identifying the endpoint of the titration. This analytical technique, known as Mohr's method, is commonly employed in industries and laboratories to accurately measure chloride ion concentrations in various solutions.
