Muaj ntau qhov kev siv tseem ceeb ntawm cov poov tshuaj ferrocyanide, suav nrog kev siv cov tshuaj no ua cov tshuaj tiv thaiv kab mob rau ob txoj kev ntsev thiab cov ntsev ntsev, hauv kev ua kom huv ntawm cov tin thiab kev sib cais ntawm tooj liab los ntawm molybdenum ores, hauv kev tsim cov cawv txiv hmab. thiab citric acid, thiab lwm yam.
Potassium ferrocyanide compound tuaj yeem lees paub tias yog cov tshuaj tsis muaj tshuaj lom uas tsis ua kom tawg los ua cyanide hauv lub cev. Hauv cov txheej txheem kev sim, qhov sib xyaw no qhia tau tias muaj toxicity tsawg heev hauv cov nas uas muaj tshuaj tuag, L50 ntawm 6400 mg / kg.
Passium Ferricyanide yog dab tsi?
Potassium ferricyanide yog ib qho inorganic compound uas muaj cov tshuaj formula K3[Fe(CN)6]. Nws yog xim liab ci xim ntsev uas muaj octahedrally sib koom ua ke hlau-cyanide complex anion. Cov khoom no yog dej-soluble, thiab tom qab yaj nyob rau hauv dej, nws tsim ib tug tov uas muaj ib tug ntsuab-daj fluorescence.
Daim duab 02: Potassium Ferricyanide
Peb tuaj yeem npaj cov poov tshuaj ferricyanide dhau los ntawm cov roj chlorine los ntawm kev daws cov poov tshuaj ferrocyanide. Ntawm no, potassium ferricyanide cais los ntawm cov tshuaj. Cov muaju ntawm cov tshuaj no muaj ib qho monoclinic crystal system. Kev sib koom ua ke geometry nyob ib ncig ntawm Fe atom yog octahedral.
Muaj cov ntawv thov tseem ceeb ntawm potassium ferricyanide; Nws yog tsuas yog siv hauv daim duab kos duab thiab hauv kev yees duab, siv los ua tus neeg sawv cev oxidizing kom tshem tawm cov nyiaj los ntawm cov xim tsis zoo thiab cov txiaj ntsig zoo thaum lub sij hawm bleaching txheej txheem, siv los ua hlau thiab hlau, muaj txiaj ntsig zoo hauv electroplating, tsim cov dyeing wool, raws li kev kuaj reagent, etc.
Qhov txawv ntawm Potassium Ferrocyanide thiab Potassium Ferricyanide yog dab tsi?
Potassium ferrocyanide thiab potassium ferricyanide yog cov tseem ceeb hauv cov tebchaw. Cov no yog cov ntsev ntsev ntawm hlau-cyanide kev sib koom ua ke. Qhov sib txawv tseem ceeb ntawm potassium ferrocyanide thiab potassium ferricyanide yog tias potassium ferrocyanide muaj Fe atom nrog +2 oxidation xeev thaum potassium ferricyanide muaj Fe atom nrog +3 oxidation xeev. Tsis tas li ntawd, qhov sib txawv yooj yim ntawm cov poov tshuaj ferrocyanide thiab potassium ferricyanide yog tias cov poov tshuaj ferrocyanide tshwm sim li txiv qaub-daj xim muaju, thaum poov tshuaj ferricyanide tshwm sim li ci liab crystals.
Ntxiv mus, potassium ferrocyanide raug suav tias yog cov tshuaj tsis muaj tshuaj lom thaum, potassium ferricyanide muaj cov tshuaj lom tsawg thiab tuaj yeem ua rau khaus rau qhov muag thiab tawv nqaij.
Cov ntawv qhia hauv qab no muab cov ntsiab lus ntawm qhov sib txawv ntawm cov poov tshuaj ferrocyanide thiab potassium ferricyanide.
Summary – Potassium Ferrocyanide vs Potassium Ferricyanide
Potassium ferrocyanide thiab potassium ferricyanide yog cov tseem ceeb hauv cov tebchaw. Cov no yog cov ntsev ntsev ntawm hlau-cyanide kev sib koom ua ke. Qhov sib txawv tseem ceeb ntawm cov poov tshuaj ferrocyanide thiab potassium ferricyanide yog tias potassium ferrocyanide muaj Fe atom nrog +2 oxidation xeev thaum potassium ferricyanide muaj Fe atom nrog +3 oxidation xeev.
