Sodium Thiosulfate
Product Code : JL-LE-11194
Sodium Thiosulfate (SKU JL-LE-11194, Model No. JL864/0137), known as hypo, is a colourless crystalline salt supplied by JaincoLab as an analytical reagent with an MSDS. It is the titrant in iodometric titrations, and its reaction with dilute hydrochloric acid, which slowly clouds the solution with sulphur, is the classic experiment for measuring how temperature and concentration affect reaction rate.

Frequently asked questions
What is the disappearing cross experiment?
Thiosulphate and acid are mixed over a pencil cross; the time until sulphur hides the cross measures the reaction rate.
