Thiosulfuric acid Usage And Synthesis
Physical propertiesThiosulfuric acid is a sulfur oxoacid. The free acid cannot be prepared by acidifying thiosulfate salts as the acid readily decomposes in water. Anhydrous methods of producing the acid are:
H2S＋ SO3→H2S2O3·nEt2O (in diethyl ether at 78°C)
Na2S2O3＋2HCl/2NaCl＋H2S2O3·2Et2O
(in diethyl ether at 78°C)
HSO3Cl＋H2S→HCl＋H2S2O3 (low temperature)
The anhydrous acid also decomposes below 0°C:
H2S2O3→H2S＋ SO3
There is another isomeric form, a white crystalline adduct of hydrogen sulfide and sulfur trioxide, H2S·SO3, which can also be prepared at low temperature.
DefinitionChEBI: Sulfurothioic S-acid is a thiosulfuric acid. It has a role as a mouse metabolite. It is a conjugate acid of a hydroxidodioxidosulfidosulfate(1-). It is a tautomer of a sulfurothioic O-acid.
