är ett [[tiosulfat]][[Salter|salt]] av [[natrium]].<br /> <br /> ==Framställning==<br /> Industriellt produceras natriumtiosulfat som en biprodukt vid tillverkningen av [[natriumsulfid]]. För laboratoriebruk så kan saltet framställas genom att värma upp [[natriumsulfit]] tillsammans med [[svavel]].<br /> :&lt;math&gt;\rm Na_2SO_3 + S \rightarrow Na_2S_2O_3&lt;/math&gt;<br /> <br /> ==Egenskaper==<br /> Natriumtiosulfat kan neutralisera [[hypoklorit]] vilket är den aktiva ingrediensen i [[klor]]baserade [[blekmedel]].<br /> :&lt;math&gt;\rm 4\ NaClO + Na_2S_2O_3 + 2\ NaOH \rightarrow 4\ NaCl + 2\ Na_2SO_4 + H_2O&lt;/math&gt;<br /> <br /> Det kan också reagera med [[guld]] och bilda molekylen Na&lt;sub&gt;3&lt;/sub&gt;[Au(S&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt;].<br /> <br /> ==Användning==<br /> *Natriumtiosulfat kan användas som ett alternativ till [[natriumcyanid]] vid utvinning av guld. Nackdelen är att guldtiosulfat-jonerna inte kan filtreras fram med [[aktivt kol]].<br /> *Som [[fixeringsvätska]] vid fotografisk [[framkallning]]. Ämnet går inom fotobranchen under namnet &#039;&#039;Hyposulfitsoda&#039;&#039; eller &#039;&#039;Hypo&#039;&#039;.<br /> *För att kunna testa [[pH]]-värdet på blekmedel. Natriumtiosulfat neutraliserar [[hypoklorit]]-joner som annars skulle ha blekt bort färgerna av [[Universell indikator|pH-indikator]]n.<br /> *[[Underkylt]] natriumtiosulfat kristalliserar sig med en [[exoterm]] reaktion vilket gör den användbar i till exempel kemiska handvärmare.<br /> *Som motgift till [[cyanid]]. Natriumtiosulfat överför svavel-atomer till cyanid som övergår i ofarlig [[tiocyanat]].<br /> *Vid [[garvning]] av [[läder]].<br /> *För att neutralisera det jod-baserade konserveringsmedlet Lugol&#039;s lösning. Lugol&#039;s konserverar tex. celler i växtplanktonprover bruna men tillsätter men Natriumtiosulfat avfärgas provet och nya färgämnen kan tillsättas.<br /> <br /> ==Se även==<br /> *[[Natriumsulfat]]<br /> <br /> [[Kategori:Natriumföreningar]]<br /> [[Kategori:Tiosulfater]]<br /> [[Kategori:Fotografiska kemikalier]]<br /> <br /> [[ar:ثيوكبريتات الصوديوم]]<br /> [[bs:Natrijum tiosulfat]]<br /> [[ca:Tiosulfat de sodi]]<br /> [[cs:Thiosíran sodný]]<br /> [[da:Natriumthiosulfat]]<br /> [[de:Natriumthiosulfat]]<br /> [[en:Sodium thiosulfate]]<br /> [[fa:سدیم تیوسولفات]]<br /> [[fr:Thiosulfate de sodium]]<br /> [[ko:싸이오황산 나트륨]]<br /> [[it:Tiosolfato di sodio]]<br /> [[he:נתרן תיוסולפט]]<br /> [[kk:Антихлор]]<br /> [[lv:Nātrija tiosulfāts]]<br /> [[hu:Nátrium-tioszulfát]]<br /> [[ms:Natrium tiosulfat]]<br /> [[nl:Natriumthiosulfaat]]<br /> [[ja:チオ硫酸ナトリウム]]<br /> [[pl:Tiosiarczan sodu]]<br /> [[pt:Tiossulfato de sódio]]<br /> [[ro:Tiosulfat de sodiu]]<br /> [[ru:Тиосульфат натрия]]<br /> [[sk:Tiosíran sodný]]<br /> [[sr:Натријум-тиосулфат]]<br /> [[fi:Natriumtiosulfaatti]]<br /> [[vi:Natri thiosunfat]]<br /> [[zh:硫代硫酸钠]]</div> Dan Olsson
