Magnesium thiosulfate is the stable magnesium salt of thiosulfuric acid, which is unstable in the free state .

Extraction and presentation

Magnesium thiosulfate is made by stirring sulfur into boiling magnesium sulfite solution:

${\displaystyle \mathrm {\ MgSO_{3}+S\rightarrow MgS_{2}O_{3}} }$

properties

Magnesium thiosulfate hexahydrate forms colorless crystals. These lose their water of crystallization at 170–420 ° C.

Magnesium thiosulfate is a reducing agent .

use

Auguste Lumière developed the intravenous injection drug magnesium thiosulfate (former trade name: Emgé) from the original photochemical.

Magnesium thiosulfate has also been used as a blood stabilizer.
