Potassium chromate thiab potassium dichromate yog cov muaj feem cuam tshuam nrog cov tshuaj inorganic uas muaj cov qauv tshuaj zoo sib xws. Lub dichromate ion hauv potassium dichromate yog tsim los ntawm kev sib xyaw ntawm ob chromate ions.
Potassium Chromate yog dab tsi?
Potassium chromate yog ib qho inorganic compound uas muaj cov tshuaj formula K2CrO4. Nws tshwm nyob rau hauv cov xim daj thiab muaj nyob rau hauv ib tug solid-state ntawm chav tsev kub. Nws yog poov tshuaj ntsev ntawm chromate anion. Qhov no yog ib qho tshuaj lom neeg hauv chav kuaj.
Daim duab 01: Potassium Chromate
Muaj ob daim ntawv crystalline ntawm potassium chromate li orthorhombic qauv thiab tetrahedral qauv. Ntawm lawv, cov qauv orthorhombic beta yog cov qauv ntau tshaj plaws, uas tuaj yeem hloov mus rau hauv alpha daim ntawv ntawm qhov kub thiab txias.
Peb tuaj yeem tsim cov poov tshuaj chromate tau yooj yim los ntawm kev kho cov poov tshuaj dichromate nrog potassium hydroxide. Lwm txoj kev ntawm kev tsim khoom yog fusion ntawm potassium hydroxide nrog chromium oxide.
Ib txwm, poov tshuaj chromate tshwm sim nyob rau hauv daim ntawv ntxhia 'tarapacaite'. Cov pob zeb no tshwm sim ua ib yam khoom tsis tshua muaj nyob hauv ntiaj teb.
Potassium chromate yog suav tias yog cov khoom carcinogenic. Qhov no yog ib yam nrog rau feem ntau ntawm cov chromium compounds paub, qhov twg chromium nyob rau hauv lub xeev oxidation +6. Ntxiv mus, qhov sib xyaw no yog corrosive, thiab nws tuaj yeem ua rau puas tsuaj lossis qhov muag tsis pom kev yog tias muaj kev sib cuag.
Potassium Dichromate yog dab tsi?
Potassium dichromate yog ib qho inorganic compound uas muaj cov tshuaj formula K2Cr2O7Nws muaj lub ntsej muag ci, liab-txiv kab ntxwv. Tsis tas li ntawd, poov tshuaj dichromate yog oxidizing tus neeg sawv cev. Yog li ntawd, muaj ntau yam kev siv ntawm no compound. Txawm li cas los xij, zoo ib yam li ntau lwm cov tshuaj chromium, poov tshuaj dichromate yog qhov ua rau peb noj qab haus huv.
Daim duab 02: Potassium Dichromate
Txog kev tsim cov poov tshuaj dichromate, muaj ob txoj hauv kev los tsim cov tshuaj no. Ib txoj hauv kev 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.
Dab tsi yog qhov zoo sib xws ntawm Potassium Chromate thiab Potassium Dichromate?
- Potassium chromate thiab potassium dichromate yog cov ionic compounds.
- Ob leeg yog ntsev ntsev.
- Cov tshuaj no muaj cov tshuaj chromate moiety.
- Ob yam khoom tseem ceeb yog qhov tseem ceeb rau kev soj ntsuam zoo thiab ntau yam ntawm cov qauv los ntawm kev tshuaj xyuas redox lossis titrations.
Qhov txawv ntawm Potassium Chromate thiab Potassium Dichromate yog dab tsi?
Potassium chromate yog ib qho inorganic compound uas muaj cov tshuaj formula K2CrO4, thaum Potassium dichromate yog ib qho inorganic compound uas muaj cov tshuaj formula K2Cr2 O7Lub dichromate ion hauv potassium dichromate yog tsim los ntawm kev sib xyaw ntawm ob chromate ions. Qhov sib txawv tseem ceeb ntawm cov poov tshuaj chromate thiab potassium dichromate yog cov poov tshuaj chromate tshwm nyob rau hauv cov xim daj thaum poov tshuaj dichromate tshwm hauv cov xim txiv kab ntxwv. Tsis tas li ntawd, poov tshuaj chromate yog tsim los ntawm kev kho cov poov tshuaj dichromate nrog poov tshuaj hydroxide thaum poov tshuaj dichromate yog tsim los ntawm cov tshuaj tiv thaiv ntawm poov tshuaj chloride thiab sodium dichromate. Yog li, qhov no yog lwm qhov sib txawv ntawm potassium chromate thiab potassium dichromate.
Ntxiv mus, cov poov tshuaj chromate yog siv rau kev sim ua haujlwm, ua tus neeg sawv cev oxidizing, hauv kev soj ntsuam zoo inorganic, raws li qhov taw qhia hauv nag lossis daus titrations, thiab lwm yam. whereas potassium dichromate yog siv los ua ib qho precursor rau potassium chrome alum (ib tshuaj siv. hauv kev lag luam tawv), rau kev tu lub hom phiaj, hauv kev tsim kho, hauv kev yees duab, thiab lwm yam.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov poov tshuaj chromate thiab potassium dichromate hauv daim ntawv.
Summary – Potassium Chromate vs Potassium Dichromate
Potassium chromate thiab potassium dichromate yog cov muaj feem xyuam nrog cov tshuaj inorganic uas muaj cov qauv tshuaj zoo sib xws. Qhov sib txawv tseem ceeb ntawm cov poov tshuaj chromate thiab potassium dichromate yog cov poov tshuaj chromate tshwm nyob rau hauv cov xim daj thaum poov tshuaj dichromate tshwm nyob rau hauv cov xim txiv kab ntxwv.
