The compound is made by combining the ion tin(IV), which carries a charge of +4, with the ion sulfite, which is an atom of sulfur and three atoms of oxygen, carrying a total charge of -2. [2] In the solid state, 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. 1 decade ago. When the protonation is conducted in diethyl ether at −78 °C, H2S2O3 (thiosulfuric acid) can be obtained. Another name for tin(IV) sulfite is stannic sulfite. Otherwise it is disulfur trioxide. I'm re-posting this question because I got a lot of hateful, ignorant responses from people about why I named my kids the way I did. Solutions of sodium thiosulfate are commonly used as a precaution in chemistry laboratories when working with bromine and for the safe disposal of bromine, iodine, or other strong oxidizers. The chief was seen coughing and not wearing a mask. Upon heating to 300 °C, it decomposes to sodium sulfate and sodium polysulfide: Thiosulfate salts characteristically decompose upon treatment with acids. It is used for both film and photographic paper processing; the sodium thiosulfate is known as a photographic fixer, and is often referred to as 'hypo', from the original chemical name, hyposulphite of soda. 1 decade ago.

Thiosulfate only if it has a 2- charge. The chief was seen coughing and not wearing a mask. [13] The alkylthiosulfates are susceptible to hydrolysis, affording the thiol. It is also used in estimating volumetrically the concentrations of certain compounds in solution (hydrogen peroxide, for instance) and in estimating the chlorine content in commercial bleaching powder and water.

Join Yahoo Answers and get 100 points today. [10], In the laboratory, this salt can be prepared by heating an aqueous solution of sodium sulfite with sulfur or by boiling aqueous sodium hydroxide and sulfur according to this equation:[11]. It could also be a thiosulfate anion, but since you said COMPOUND, and not ion, as well as the fact that there is no charge listed in your formula, I'm going to assume it's not an anion. In pH testing of bleach substances, sodium thiosulfate neutralizes the color-removing effects of bleach and allows one to test the pH of bleach solutions with liquid indicators. This process is used to demonstrate the concept of reaction rate in chemistry classes. [12] It can, when heated with a sample containing aluminium cations, produce a white precipitate: Alkylation of sodium thiosulfate gives S-alkylthiosulfates, which are called Bunte salts. thanks.

It could also be a thiosulfate anion, but since you said COMPOUND, and not ion, as well as the fact that there is no charge listed in your formula, I'm going to assume it's not an anion. Common compound names. Some problems with this alternative process include the high consumption of thiosulfate, and the lack of a suitable recovery technique, since [Au(S2O3)2]3− does not adsorb to activated carbon, which is the standard technique used in gold cyanidation to separate the gold complex from the ore slurry. Otherwise it is disulfur trioxide. 5H2O is also a component of iodine clock experiments. The S-S distance indicates a single bond, implying that the terminal sulfur holds a significant negative charge and the S-O interactions have more double-bond character. Why does diethyl ether have the smallest dipole? Under normal conditions, acidification of solutions of this salt excess with even dilute acids results in complete decomposition to sulfur, sulfur dioxide, and water:[10]. double displasment, single displacement, neutralize)? What is the IUPAC name for ch3-ch2-c(double bond o)-ch3. Sodium thiosulfate and ammonium thiosulfate are a component of an alternative lixiviants to cyanide for extraction of gold. Answer Save. What is the IUPAC name for ch3-ch2-c(double bond o)-ch3? 0 0 ♥falling.from.grace. The anhydrous salt exists in several polymorphs. I'd like to first start by clearing up a few misunderstandings. Sulfurous acid (also Sulfuric(IV) acid) is the chemical compound with the formula H 2 SO 3.There is no evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase.

Relevance. It should be written as S2032-. thiosulfate (: 0 0. This reaction is illustrated by one synthesis of thioglycolic acid: InChI=1S/2Na.H2O3S2/c;;1-5(2,3)4/h;;(H2,1,2,3,4)/q2*+1;/p-2, InChI=1/2Na.H2O3S2/c;;1-5(2,3)4/h;;(H2,1,2,3,4)/q2*+1;/p-2, Except where otherwise noted, data are given for materials in their, World Health Organization's List of Essential Medicines, Institute for Occupational Safety and Health, https://en.wikipedia.org/w/index.php?title=Sodium_thiosulfate&oldid=983064125, World Health Organization essential medicines, Chemical articles with multiple compound IDs, Multiple chemicals in an infobox that need indexing, Chemical articles with multiple CAS registry numbers, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, 48.3 °C (118.9 °F; 321.4 K) (pentahydrate), 100 °C (212 °F; 373 K) (pentahydrate, - 5H, This page was last edited on 12 October 2020, at 01:18.

[8] Ammonium thiosulfate is typically preferred to sodium thiosulfate for this application.[2]. Actually, "ethanol" is incorrect. The relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (active ingredient in bleach) and in so doing becomes oxidized to sulfate. Favorite Answer.
