Iodometry is a standard method for redox titration. In many indirect methods one lets the analyte (the substance whose concentration is to be determined) react with iodide ions as then forms triiodide ions, I3- . The amount of triiodide ions is then determined by titration with thiosulphate ions, S2O32- which then form tetrathionate ions, S4O62- whereby the triiodide ions change into iodide ions. Determine the mass of triiodide ions in a solution from the following data. The sample containing triiodide ions was titrated with a 0.01002 M sodium thiosulfate solution of which 18.38 mL were required.
