| Description | Thiosulfate, also known as thiosulfuric acid or [so2(OH)(SH)], belongs to the class of inorganic compounds known as non-metal thiosulfates. These are inorganic non-metallic compounds containing a thiosulfate as its largest oxoanion. Thiosulfate is an extremely strong acidic compound (based on its pKa). Sodium thiosulfate has been considered as an empirical treatment for cyanide poisoning, along with hydroxocobalamin. Thiosulfate exists in all living species, ranging from bacteria to humans. Sodium thiosulfate, commonly called hypo (from "hyposulfite"), was widely used in photography to fix black and white negatives and prints after the developing stage; modern 'rapid' fixers use ammonium thiosulfate as a fixing salt because it acts three to four times faster. Thiosulfates react with halogens differently, which can be attributed to the decrease of oxidizing power down the halogen group:2 S2O2−3 (aq) + I2 (aq) → S4O2−6 (aq) + 2 I− (aq)S2O2−3 (aq) + 4 Br2 (aq) + 5 H2O(l) → 2 SO2−4 (aq) + 8 Br− (aq) + 10 H+ (aq)S2O2−3 (aq) + 4 Cl2 (aq) + 5 H2O (l) → 2 SO2−4 (aq) + 8 Cl− (aq) + 10 H+ (aq)In acidic conditions, thiosulfate causes rapid corrosion of metals; steel and stainless steel are particularly sensitive to pitting corrosion induced by thiosulfate. Addition of molybdenum to stainless steel is needed to improve its resistance to pitting (AISI 316L hMo). Thiosulfate extensively forms complexes with transition metals hence a common use is dissolving silver halides in film photography developing. The prefix thio- indicates that the thiosulfate ion is a sulfate ion with one oxygen replaced by sulfur. Hydroxidodioxidosulfidosulfate was first documented in 1977 (PMID: 856920). Thiosulfate occurs naturally and is produced by certain biochemical processes (PMID: 12011515) (PMID: 1681358) (PMID: 6600205) (PMID: 1943059). |
