Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na 2 S 2 O 3 ·(H 2 O) x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water.
Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S 2 O 2− 3.Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid, such as sodium thiosulfate Na 2 S 2 O 3 and ammonium thiosulfate (NH 4) 2 S 2 O 3.
The agent used is sodium thiosulfate, and reacts according to the following equation: [2] AgX(s) + 2 Na 2 S 2 O 3 (aq) → Na 3 [Ag(S 2 O 3) 2](aq) + NaX(aq) An indefinite number of positive prints can be generated from the negative by passing light through it and undertaking the same steps outlined above.

Sodium thiosulfate, also spelled sodium thiosulphate, is used as a medication to treat cyanide poisoning, pityriasis versicolor, and to decrease side effects from cisplatin. [ 3 ] [ 4 ] [ 5 ] For cyanide poisoning, it is often used after the medication sodium nitrite and is typically only recommended for severe cases.
Thioglycolic acid is prepared by reaction of sodium or potassium chloroacetate with alkali metal hydrosulfide in aqueous medium. [19] It can be also prepared via the Bunte salt obtained by reaction of sodium thiosulfate with chloroacetic acid: [7] [20] ClCH 2 CO 2 H + Na 2 S 2 O 3 → Na[O 3 S 2 CH 2 CO 2 H] + NaCl Na[O 3 S 2 CH 2 CO 2 H] + H 2 ...
It is possible to calculate the number of moles of Fe 2+ ions by using a colorimeter, because of the very intense color of Prussian blue. In physiology experiments potassium ferricyanide provides a means increasing a solution's redox potential (E°' ~ 436 mV at pH 7). As such, it can oxidize reduced cytochrome c (E°' ~ 247 mV at pH 7) in ...
Sodium tetrathionate is formed by the oxidation of sodium thiosulfate (Na 2 S 2 O 3), e.g. by the action of iodine: [1] 2 Na 2 S 2 O 3 + I 2 → Na 2 S 4 O 6 + 2 NaI. The reaction is signaled by the decoloration of iodine. This reaction is the basis of iodometric titrations. Other methods include the coupling of sodium bisulfite with disulfur ...
