Title: Estimation of Chlorides by Titration
Chlorides can be estimated by titration with a standard silver nitrate solution. The process involves the use of a suitable indicator to determine the endpoint of the reaction.
Indicator:
Potassium chromate is used as an indicator in the estimation of chlorides by titration. It acts as an indicator by forming a red precipitate of silver chromate when all the chlorides are precipitated as silver chloride. The appearance of the red precipitate signals the endpoint of the reaction.
Benefits of Potassium Chromate:
Potassium chromate is preferred over other indicators such as potassium dichromate or potassium manganate because of its distinct color change and ability to form a stable precipitate with silver ions. The red color of the silver chromate is easily visible against the white background of the silver chloride precipitate, making it easy to determine the endpoint of the reaction.
Conclusion:
In conclusion, the estimation of chlorides by titration requires the use of a suitable indicator to determine the endpoint of the reaction. Potassium chromate is the preferred indicator due to its distinct color change and ability to form a stable precipitate with silver ions.
