Thiosulfate Information

$35.00

The K-9705 Thiosulfate Kit was designed to accurately measure the levels of Thiosulfate in water from 5-50 ppm. K-9705 uses the Iodometric MethodCHEMetrics' sulfite test kits employ the iodometric chemistry in which sulfite is titrated with iodide-iodate titrant in an acid solution using a starch indicator. Thiosulfate will titrate as sulfite. Sulfamic acid is added to the sample to prevent interference from nitrite. Results are expressed as ppm (mg/L) SO3.

Thiosulfate is an excellent reducing agent. It is used primarily as an antichlor, or chlorine-removing agent, in various chemical processes, including the bleaching of pulp, paper, and textiles
