	Sodium thiosulfate - Wikipedia, the free encyclopedia
		The thiosulfate anion is tetrahedral in shape and is notionally derived by replacing one of the oxygen atoms by a sulfur atom in a sulfate anion.
		Perhaps most notably in the laboratory, the thiosulfate anion reacts stoichiometrically with iodine, reducing it to iodide as it is oxidized to tetrathionate:
		The thiosulfate ion can decompose into the sulfite ion and a colloidal suspension of sulfur, which is opaque.

		Thiosulfate is also useful in the extraction of silver from silver ore, in leather manufacture, and as a mordant in the textile industry.
		Thiosulfate is manufactured by some cells by oxidation of elemental sulfur and by degradation of L-cysteine.
		Thiosulfate is used as a titrant in the procedure.

		Sodium thiosulfate is considered to be essentially a nontoxic drug, although nausea and vomiting have been described with rapid IV administration of antidotal doses to normal adult human volunteers.
		Sodium thiosulfate is not considered to be a reproductive or developmental toxicant due to its rapid breakdown in the body to normal constituents, (i.e.
		When sodium thiosulfate is coadministered with cisplatin (a chemotherapeutic agent that often causes nephrotoxicity), inactive mobile metabolites of cisplatin are formed by a direct reaction between cisplatin and sodium thiosulfate in the systemic circulation, which results in a reduction in the amount of cisplatin in the kidney.

		The sodium thiosulfate will be used as a pretreatment for the water in tank mixes to remove chlorine or other reactant species, thus functioning as a dechlorinator or reducing agent.
		Variations in excretion of thiosulfate are related to the extent of protein metabolism, activity of the intestinal flora, and the sulfur-amino acid content of the diet.
		Considering that thiosulfate can be metabolized by sulfate-reducing bacteria, and given its ability to react with chlorine (to act as a reducing agent), sodium thiosulfate is unlikely to occur in drinking water.

		Sodium thiosulfate (Na2S2O3) is a reducing agent that reacts with oxidizing agents, specifically, hypochlorous acid (HOCl) which is the active ingredient in household bleach, according the reaction: HOCl + 2(S2O3)^-2 -----------> Cl^-1 + (S4O6)^-2 + OH^-1 Unfortunately, it does not react with organic chlorine compounds such as PCB's, etc. to neutralize them.

	Medical Dictionary: Sodium thiosulfate - WrongDiagnosis.com
		Sodium thiosulfate: A water soluble salt and reducing agent that reacts with oxidizing agents.
		Although its exact mechanism of action is unknown, thiosulfate likely provides an exogenous source of sulfur, thereby hastening the detoxification of cyanide through the enzyme rhodanese (thiosulfate cyanide sulfurtransferase) which converts cyanide to the relatively nontoxic, excretable thiocyanate ion.
		In addition, this agent neutralizes the reactive alkylating species of nitrogen mustard and may decrease cutaneous toxicity related to nitrogen mustard extravasation.

		For the trouble to mix and use your own Amonium thiosulfate fixer you could just treat your Hypham-fixed prints in Kodalk as a pre-treatment for toning for five minutes --that is, if this is the goal.
		An important note is that Amonium Thiosulfate fixers used with extended fixing times will produce argentothiosulfates which are difficult to wash out of a print (see The Photographer's Cookbook).
