Titration of potassium chloride
WebMar 8, 2024 · Chlorine concentration is determined by titration with sodium thiosulfate using a redox electrode. Acetate buffer and potassium iodide are added to the sample, leading to the formation of iodine upon reaction with chlorine. The iodine in the sample is then titrated directly with sodium thiosulfate, and is proportional to the concentration of ... WebApr 9, 2024 · It’s a direct titration method. In this method silver nitrate is used as titrant and chloride ion solution as analyte. Potassium chromate is used as an indicator. At the end point, when all chloride ions are consumed by silver ions, reddish brown colored precipitate is formed by reaction of silver ions and chromate ions.
