Qhov sib txawv tseem ceeb ntawm cov poov tshuaj permanganate thiab potassium dichromate yog cov poov tshuaj permanganate muaj xim liab doog, thaum potassium dichromate muaj xim liab-txiv kab ntxwv.
Potassium permanganate thiab potassium dichromate muaj ntau heev hauv chav kuaj vim peb feem ntau siv lawv hauv cov txheej txheem titration. Txawm hais tias ob lub tebchaw no muaj cov poov tshuaj ua cov khoom sib xyaw, peb tuaj yeem paub qhov txawv ntawm lawv yooj yim los ntawm kev saib lawv vim lawv muaj qhov sib txawv heev.
Potassium Permanganate yog dab tsi?
Potassium permanganate yog ib qho inorganic compound uas muaj cov tshuaj formula KMnO4Yog li, lub compound yog ntsev ntawm poov tshuaj vim nws muaj ob ions, K+ thiab MnO4-. Cov hlau manganese nyob rau hauv +7 oxidation xeev. Cov compound muaj nyob rau hauv cov khoom hauv lub xeev ntawm chav tsev kub thiab tshwm raws li ib tug tsaus liab doog khoom compound. Tsis tas li ntawd, nws yog ib qho tshuaj tseem ceeb los ntxuav qhov txhab.
Daim duab 01: Ib qho piv txwv ntawm Potassium Permanganate
Ntxiv mus, poov tshuaj permanganate yog cov muaj zog oxidizing tus neeg sawv cev. Nws yog dej soluble, thiab thaum yaj hauv dej, nws muab cov xim liab los yog xim liab. Cov evaporation ntawm cov dej los ntawm cov tshuaj no ua rau tsaus liab doog, glistening crystals.
Tsis tas li ntawd, qhov sib xyaw no yog cov oxidant muaj zog uas tsis tsim cov khoom muaj kuab lom. Yog li, nws muaj txiaj ntsig zoo hauv kev siv sib txawv. Cov teb ntawm daim ntawv thov muaj xws li tshuaj, kev kho dej, synthesis ntawm cov organic tebchaw, khaws txiv hmab txiv ntoo, thiab lwm yam.
Potassium Dichromate yog dab tsi?
Potassium dichromate yog ib qho inorganic compound uas muaj cov tshuaj formula K2Cr2O7Cov khoom sib xyaw muaj qhov ci, liab-txiv kab ntxwv tsos. Tsis tas li ntawd, nws yog ib qho oxidizing tus neeg sawv cev. Yog li ntawd, muaj ntau yam kev siv ntawm no compound. Txawm li cas los xij, zoo li ntau cov chromium tebchaw, potassium dichromate ib yam nkaus ua rau peb noj qab haus huv.
Daim duab 02: Ib qho piv txwv ntawm Potassium Dichromate
Los ntawm kev tsim khoom, muaj ob txoj hauv kev los tsim cov poov tshuaj dichromate. Ib qho yog los ntawm cov tshuaj tiv thaiv ntawm potassium chloride thiab sodium dichromate. Txoj kev thib ob yog los ntawm kev ci cov chromate ore nrog potassium hydroxide.
Ntxiv mus, potassium dichromate tau yooj yim yaj hauv dej, thiab thaum tawg, nws nkag mus rau ionization. Thaum xav txog cov ntawv thov, nws yog siv los ua tus thawj coj rau potassium chrome alum (ib tshuaj siv hauv kev lag luam tawv). Tsis tas li ntawd, nws kuj yog siv los ntxuav lub hom phiaj, hauv kev tsim, hauv kev yees duab, thiab lwm yam.
Qhov txawv ntawm Potassium Permanganate thiab Potassium Dichromate yog dab tsi?
Potassium permanganate yog ib qho inorganic compound uas muaj cov tshuaj formula KMnO4 while potassium dichromate yog ib qho inorganic compound uas muaj cov tshuaj formula K 2 Cr2O7 Qhov sib txawv tseem ceeb ntawm cov poov tshuaj permanganate thiab potassium dichromate yog cov poov tshuaj permanganate muaj xim liab doog, whereas potassium dichromate muaj xim liab. -txiv kab ntxwv. Thaum xav txog oxidation xeev ntawm cov hlau atoms nyob rau hauv cov tebchaw, manganese nyob rau hauv poov tshuaj permanganate muaj +7 oxidation lub xeev uas chromium nyob rau hauv poov tshuaj dichromate muaj +6 oxidation xeev.
Cov duab hauv qab no qhia ntau qhov sib piv ntsig txog qhov sib txawv ntawm cov poov tshuaj permanganate thiab potassium dichromate.
Summary – Potassium Permanganate vs Potassium Dichromate
Potassium permanganate thiab potassium dichromate yog poov tshuaj ntsev. Qhov sib txawv tseem ceeb ntawm cov poov tshuaj permanganate thiab potassium dichromate yog cov poov tshuaj permanganate muaj xim tsaus nti, thaum potassium dichromate muaj xim liab-txiv kab ntxwv.
