Iodine thiosulfate
Web17 apr. 2024 · One question for clarification: You think the Iodine interacted with the sodium thiosulphate, forming some I X − which then lead to the reaction I X − + I X 2 + starch ↔ dark blue starch? And when adding more and more thiosulphate all of the I 2 and consequently all of the dark blue starch reacted to the colourless I X −? – user86728 WebName_____ Determination of Iodine Concentration by Titration Dr. Slotsky. Reaction: 2 Na 2 S 2 O 3 + I 2 Na 2 S 4 O 6 + 2 NaI Introduction: The above reaction shows that 2 moles of sodium thiosulfate react with one mole of elemental iodine. We can use this to determine the concentration of iodine in a solution.
