- Thiosulfate ions are oxidised and iodine is reduced.
- Iodine/thiosulfate titrations can be used to determine the ClO- content in household bleach, the Cu2+ content in copper(II) compounds, and the Cu content in copper alloys.
- Add a standard solution of Na2S2O3 to the burette.
- Prepare a solution of the oxidising agen to be analysed. Using a pipette, add this solution to the conical flask. Then add an excess of potassium iodide. The oxising agent reacts with iodide ions to…
