Answer:

Sodium thiosulfate is often standardized with potassium dichromate. In the standardization, iodine (triiodide) liberated by potassium dichromate in an acidic potassium iodide solution is titrated with a sodium thiosulfate solution. The iodine liberation process significantly affects the titration results.
