  2. Sodium thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_thiosulfate

    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. The compound is a reducing agent and a ligand, and these properties underpin its applications. [2]

  3. Thiosulfate - Wikipedia

    en.wikipedia.org/wiki/Thiosulfate

    Thiosulfate is an acceptable common name and used almost always. The functional replacement IUPAC name is sulfurothioate; the systematic additive IUPAC name is trioxidosulfidosulfate(2−) or trioxido-1κ 3 O-disulfate(S—S)(2−). [1] Thiosulfate also refers to the esters of thiosulfuric acid, e.g. O,S-dimethyl thiosulfate CH 3 −O−S(=O) 2 ...

  5. Sodium thiosulfate (medical use) - Wikipedia

    en.wikipedia.org/wiki/Sodium_thiosulfate...

    Sodium thiosulfate is a classical antidote to cyanide poisoning, [10] For this purpose it is used after the medication sodium nitrite and typically only recommended for severe cases. [4] [6] It is given by injection into a vein. [4] In this use, sodium nitrite creates methemoglobinemia which removes cyanide from mitochondria. [6]

  6. Iodine clock reaction - Wikipedia

    en.wikipedia.org/wiki/Iodine_clock_reaction

    This clock reaction uses sodium, potassium or ammonium persulfate to oxidize iodide ions to iodine. Sodium thiosulfate is used to reduce iodine back to iodide before the iodine can complex with the starch to form the characteristic blue-black color. Iodine is generated: 2 I − + S 2 O 2− 8 → I 2 + 2 SO 2− 4. And is then removed:

    The thiosulfate anion (S 2 O 2− 3) Sodium thiosulfate, a salt containing the thiosulfate anion; S 2 O 2− 2, a reported sulfur oxyanion. However salts containing S 2 O 2− 2 and HS 2 O − 2 are not well characterized; they would be conjugate bases derived from the parent thiosulfurous acid (H 2 S 2 O 2), which is also of doubtful existence ...

  8. Sodium aurothiosulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_aurothiosulfate

    Sodium aurothiosulfate, or sanocrysin, is the inorganic compound with the formula Na 3 [Au(S 2 O 3) 2]·2H 2 O. It is the trisodium salt of the coordination complex of gold(I), [Au(S 2 O 3) 2] 3−. The dihydrate, which is colorless, crystallizes with two waters of crystallization.

  9. Sodium tetrathionate - Wikipedia

    en.wikipedia.org/wiki/Sodium_tetrathionate

    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 ...
