ANALYSIS OF BLEACH BY THIOSULFATE TITRATION
seniorchem.comWeigh out approximately 12.5 g of sodium thiosulfate pentahydrate crystals into a 250 mL volumetric flask and add approximately 0.025g sodium carbonate. Make up to the mark with distilled water. Sample results and calculations: Mass of sodium thiosulfate = 12.62 g C = …
An iodine / thiosulfate titration
mccscience.yolasite.comagainst sodium thiosulfate solution. The sodium thiosulfate solution is placed in the burette and, as it is added to the conical flask, it reacts with the iodine and the colour of the solution fades. When it reaches a pale yellow colour, a few drops of a freshly prepared starch solution are added.
Determination of Ethanol Concentration in Aqueous Solutions
www.canterbury.ac.nz8. Fill a burette with sodium thiosulfate solution and titrate each flask with sodium thiosulfate. When the brown iodine colour fades to yellow (figure 2), add 1 mL of starch solution and keep titrating until the blue colour disappears (figures 3-5). Titrate the blank flasks first, and repeat until concordant results are obtained
