<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Sodium Thiosulfate&#039;&#039;&#039; (also known as [[sodium hyposulfite]] or &quot;hypo&quot;) is an [[inorganic compound]] represented by the formula Na2S2O3. It is a colorless, crystalline solid that is more commonly encountered as a pentahydrate, Na2S2O3•5H2O. Sodium thiosulfate has a wide range of uses in various industries, including [[photography]], [[medicine]], and [[water treatment]].<br /> <br /> ==Chemical Properties==<br /> Sodium thiosulfate is an [[ionic compound]] made up of two [[sodium]] ions (Na+) and one thiosulfate ion (S2O3-). The thiosulfate ion is a [[polyatomic ion]] in which two [[sulfur]] atoms are bonded to three [[oxygen]] atoms. One of the sulfur atoms has an oxidation state of +6 and the other has an oxidation state of +2. The overall charge of the ion is -2.<br /> <br /> ==Production==<br /> Sodium thiosulfate is produced industrially by the reaction of [[sodium sulfite]] with sulfur. Alternatively, it can be produced by boiling [[sodium sulfide]] with sulfur.<br /> <br /> ==Uses==<br /> ===Photography===<br /> In [[photography]], sodium thiosulfate is used as a [[fixing agent]] to dissolve unaltered silver salts from exposed [[photographic film]] or [[photographic paper]].<br /> <br /> ===Medicine===<br /> In [[medicine]], sodium thiosulfate is used as an antidote to [[cyanide poisoning]]. It works by converting the poisonous cyanide into thiocyanate, a compound that is less toxic and can be excreted in urine.<br /> <br /> ===Water Treatment===<br /> In [[water treatment]], sodium thiosulfate is used to dechlorinate tap water including lowering [[chlorine]] levels for use in aquariums.<br /> <br /> ==Safety==<br /> Sodium thiosulfate is generally considered safe for handling. However, exposure to large amounts can cause irritation to the eyes, skin, and respiratory tract.<br /> <br /> ==See Also==<br /> * [[Sodium sulfite]]<br /> * [[Sodium sulfide]]<br /> * [[Cyanide poisoning]]<br /> <br /> [[Category:Inorganic compounds]]<br /> [[Category:Sodium compounds]]<br /> [[Category:Photographic chemicals]]<br /> [[Category:Antidotes]]<br /> {{Inorganic-compound-stub}}<br /> {{Chemistry-stub}}<br /> {{Medicine-stub}}</div>
