Product Short Description:
The determination of sulfite usually is made only on boiler waters or on waters that have been treated with catalyzed sodium sulfite for corrosion prevention.

Product Description:
Summary of Method The water sample is acidified and titrated with a potassium iodide-iodate standard solution. The acid releases free iodine, which is reduced to colorless iodide by the sulfite in the sample. When all of the sulfite is gone, the iodine reacts with the starch indicator to form a blue color.

Product Short Description:
Standard potassium iodide-iodate titrant standardized to 0.0125N . Titrate with potassium iodide-iodate titrant until end point and faint permanent blue color develops.
