är en [[kemisk förening]] med formeln K&lt;sub&gt;3&lt;/sub&gt;Fe(CN)&lt;sub&gt;6&lt;/sub&gt;.<br /> <br /> ==Blodlutsalt==<br /> När forna tiders [[alkemist]]er kokade [[blod]] tillsammans med [[pottaska]] fann de att det bildades ett vattenlösligt [[salter|salt]]. Beroende på hur mycket [[syre]] som lösningen utsattes för under uppvärmningen så blev saltet antingen gult eller rött. Därav namnen rött respektive [[gult blodlutsalt]].<br /> <br /> ==Framställning==<br /> Kaliumferricyanid framställs idag genom [[oxidering]] av [[kaliumferrocyanid]] med till exempel [[klor]]gas eller [[väteperoxid]].<br /> :&lt;math&gt;\rm 2\ K_4Fe(CN)_6 + Cl_2 \rightarrow 2\ K_3Fe(CN)_6 + 2\ KCl&lt;/math&gt;<br /> <br /> :&lt;math&gt;\rm 2\ K_4Fe(CN)_6 + H_2O_2 \rightarrow 2\ K_3Fe(CN)_6 + 2\ KOH&lt;/math&gt;<br /> <br /> ==Användning==<br /> En blandning av kaliumferricyanid och [[fenolftalein]] kallas &#039;&#039;Ferroxylindikatorlösning&#039;&#039;. Lösningen är i normala fall färglös, men blir blå (genom bildandet av [[berlinerblått]]) om det utsätts för Fe&lt;sup&gt;2+&lt;/sup&gt;-joner och rosa i kontakt med [[hydroxid]]-joner. Lösningen används för att upptäcka oxiderat järn på ytor av [[stål]] innan de leder till [[rost]].<br /> <br /> Kaliumferricyanid används också inom [[mörkrumsteknik|fototeknik]], [[härdning]] och [[Färgämne|färgning]].<br /> <br /> ==Se även==<br /> * [[Kaliumferrocyanid]]<br /> * [[Berlinerblått]]<br /> <br /> [[Kategori:Kaliumföreningar]]<br /> [[Kategori:Järnföreningar]]<br /> [[Kategori:Cyanider]]<br /> <br /> [[ca:Ferricianur de potassi]]<br /> [[cs:Hexakyanoželezitan draselný]]<br /> [[de:Kaliumhexacyanidoferrat(III)]]<br /> [[el:Σιδηρικυανιούχο κάλιο]]<br /> [[en:Potassium ferricyanide]]<br /> [[es:Ferricianuro de potasio]]<br /> [[fa:پتاسیم فری‌سیانید]]<br /> [[fr:Ferricyanure de potassium]]<br /> [[it:Ferricianuro di potassio]]<br /> [[lv:Kālija heksacianoferāts (III)]]<br /> [[nl:Kaliumhexacyanoferraat(III)]]<br /> [[ja:フェリシアン化カリウム]]<br /> [[pl:Żelazicyjanek potasu]]<br /> [[pt:Ferricianeto de potássio]]<br /> [[ro:Fericianură de potasiu]]<br /> [[ru:Гексацианоферрат(III) калия]]<br /> [[sk:Hexakyanoželezitan draselný]]<br /> [[uk:Гексаціаноферат (III) калію]]<br /> [[zh:铁氰化钾]]</div> Dan Olsson
