What is the procedure for the standardization of sodium thiosulfate?
Thiosulfate can be standardised by adding excess potassium iodide solution to a known volume of a standard acidified solution of potassium dichromate, and then titrating the liberated iodine against the sodium thiosulfate solution.http://www.meduniv.lviv.ua/files/kafedry/tokshim/English/Analytical/Manuals_Analytchem/Iodometry.pdf

How does potassium and sodium thiosulphate turn yellow?
Potassium and sodium thiosulfate can turn yellow due to the formation of a colored complex with iodine. When iodine is added to a solution containing thiosulfate, it forms a triiodide ion which has a yellow color. This reaction is commonly used in chemistry as an indicator for the presence of thiosulfate ions in solution.
Why is potassium iodide added to an organic layer before titration with sodium thiosulfate?
Potassium iodide is added to an organic layer before titration with sodium thiosulfate to facilitate the formation of iodine from the oxidation of iodide ions. This iodine can then be titrated with sodium thiosulfate, allowing for the quantitative analysis of oxidizing agents present in the organic layer. The reaction between iodine and thiosulfate is well-defined and allows for accurate determination of the concentration of the oxidizing species.
How many moles of Na2S2O3 react with one mole of KClO3 used in the standardization?
Standardization of sodium thiosulfate uses potassium iodate with excess potassium iodide and acidified. Iodine is liberated and that is titrated with sodium thiosulfate. KIO3 + 5KI + 3H2SO4 -----> 3K2SO4 + 3H2O + 3 I2 I2 + 2Na2S2O3 -------> 2NaI + Na2S4O6 So 1 mole of KIO3 produces 3 moles of Iodine. 1 moles of iodine reacts with 2 moles of thiosulfate. So 6 moles of sodium thiosulfate react with 1 mole of potassium iodate KIO3.
How is standard Na2S2O3 solution carried out?
A standard Na₂S₂O₃ (sodium thiosulfate) solution is typically prepared by dissolving a precise amount of the anhydrous or pentahydrate form of sodium thiosulfate in distilled water to achieve a desired molarity. The solution is then standardized using a primary standard, such as potassium dichromate (K₂Cr₂O₇), through a redox titration process. This involves adding the thiosulfate solution to a known concentration of dichromate until the endpoint is reached, which is often indicated by a color change. Proper storage in a dark container is essential to prevent decomposition of the thiosulfate solution.
