Qhov sib txawv tseem ceeb ntawm cov poov tshuaj permanganate thiab poov tshuaj manganate yog cov poov tshuaj permanganate zoo li ntshav-bronze koob-puab crystals, whereas poov tshuaj manganate tshwm li ntsuab crystals.
Potassium permanganate thiab potassium manganate feem ntau tsis meej pem vim lawv cov npe zoo sib xws thiab tshwm sim. Txawm li cas los xij, lawv txawv ntawm cov khoom siv tshuaj thiab lub cev.
Potassium Permanganate yog dab tsi?
Potassium permanganate yog ib qho inorganic compound uas muaj cov tshuaj formula KMnO4 Nws yog ib qho ionic compound (ib ntsev ntawm poov tshuaj) uas muaj cov poov tshuaj cation ua ke nrog manganite anion. Cov tshuaj no yog ib qho muaj zog oxidizing tus neeg sawv cev. Qhov no yog vim nws tuaj yeem txo qis los ntawm manganese atom hauv anion; manganese nyob rau hauv no compound yog nyob rau hauv ib tug +7 oxidation xeev, uas yog lub siab tshaj plaws oxidation lub xeev nws muaj peev xwm nyob rau hauv. Yog li ntawd, nws yuav yooj yim txo mus rau hauv qis oxidation xeev los ntawm oxidizing lwm oxidizable compounds.
Daim duab 01: Pom ntawm Potassium Permanganate
Potassium permanganate tshwm sim hauv cov khoom-lub xeev ntawm chav tsev kub. Nws zoo li rab koob zoo li cov qauv uas muaj xim liab doog. Nws yog dej-soluble heev, thiab thaum yaj, nws tsim cov xim liab doog xim. Peb tuaj yeem tsim cov poov tshuaj permanganate hauv kev lag luam los ntawm kev sib xyaw ntawm manganese oxide nrog poov tshuaj hydroxide, ua raws li cua sov hauv huab cua.
Muaj ntau qhov kev siv cov tshuaj poov tshuaj permanganate hauv ntau qhov chaw xws li kev siv kho mob, kev kho dej, kev sib txuas ntawm cov organic sib txuas, kev siv tshuaj ntsuam xyuas xws li titrations, kev txuag txiv hmab txiv ntoo, suav nrog cov khoom siv ciaj sia raws li cov khoom siv hluav taws xob hypergolic, thiab lwm yam.
YPotassium Manganate yog dab tsi?
Potassium manganate yog ib qho inorganic compound uas muaj cov tshuaj formula K2MNO4. Nws tshwm sim raws li cov xim ntsuab xim ntsev sib xyaw uas tuaj yeem pom tau los ua ib qho nruab nrab hauv kev lag luam synthesis ntawm poov tshuaj permanganate.
Daim duab 02: Potassium Manganate
Cov tshuaj lom neeg no muaj cov poov tshuaj cations thiab manganate anions, thiab cov anion yog tetrahedral ion uas Mn-O daim ntawv cog lus ntev dua Mn-O daim ntawv cog lus hauv potassium permanganate. Ntxiv mus, qhov sib xyaw no yog isostructural nrog potassium sulfate.
Peb tuaj yeem tsim cov poov tshuaj manganate los ntawm kev kho MnO2 nrog huab cua. Nws muab cov xim ntsuab-xim yaj. Raws li lwm txoj hauv kev, peb tuaj yeem siv cov poov tshuaj nitrate ua oxidizer tsis yog cua. Txawm li cas los xij, ntawm chav ntsuas ntsuas, peb tuaj yeem tsim cov poov tshuaj manganate los ntawm cua sov cov tshuaj ntawm poov tshuaj permanganate nyob rau hauv lub xub ntiag ntawm ib tug concentrated KOH kua tom qab txias, uas muab ntsuab crystals.
Qhov txawv ntawm Potassium Permanganate thiab Potassium Manganate
Potassium permanganate yog ib qho inorganic compound uas muaj cov tshuaj formula KMnO4,hos poov tshuaj manganate yog ib qho inorganic compound uas muaj cov tshuaj formula K2MNO4. Qhov sib txawv tseem ceeb ntawm poov tshuaj permanganate thiab poov tshuaj manganate yog cov poov tshuaj permanganate zoo li ntshav-bronze koob-zoo li cov muaju, thaum poov tshuaj manganate zoo li ntsuab crystals.
Ntxiv mus, potassium permanganate yog cov siv lead ua orthorhombic thaum potassium manganate yog isomorphous nrog K2SO4. Ntxiv rau qhov sib txawv no, poov tshuaj permanganate yog tsim los ntawm manganese dioxide, thaum poov tshuaj manganate yog tsim los ntawm kev kho MnO2 nrog huab cua.
Cov ntawv qhia hauv qab no qhia qhov sib txawv ntawm cov poov tshuaj permanganate thiab potassium manganate hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Potassium Permanganate vs Potassium Manganate
Potassium permanganate yog ib qho inorganic compound uas muaj cov tshuaj formula KMnO4,thaum Potassium manganate yog ib qho inorganic compound uas muaj cov tshuaj formula K2MNO4. Qhov sib txawv tseem ceeb ntawm poov tshuaj permanganate thiab poov tshuaj manganate yog cov poov tshuaj permanganate zoo li ntshav-bronze koob-zoo li cov muaju, thaum poov tshuaj manganate zoo li ntsuab crystals.
