Sodium tetrathionate dihydrate. 1 Structures Expand this section. A spectroscopic investigation into the reaction of sodium tetrathionate with cysteine at pH 5 both at the boil and at room temperature has been carried out. The crystal structure of potassium tetrathionate is monoclinic with a=22.081 o, b=7.991 o, c=10.108 o. As a further example of the use of anhydrous solvents in which water is readily soluble, anhydrous isopropanol has been observed to react similarly to anhydrous ethanol, though distinctly at a slower rate.
