Qhov sib txawv tseem ceeb ntawm KH2PO4 thiab K2HPO4 yog KH2PO4 yog monobasic thiab tuaj yeem tso cov poov tshuaj tsawg thaum K2HPO4 yog dibasic thiab tuaj yeem tso cov poov tshuaj ntau thaum siv hauv chiv.
Cov ntsiab lus monobasic thiab dibasic hais txog cov poov tshuaj cations khi rau phosphate molecule. Hauv lwm lo lus, monobasic compound tuaj yeem siv tsuas yog ib qho hydrogen ion lossis proton xwb, thaum lub dibasic compound tuaj yeem nqa mus txog ob lub hydrogen ions lossis protons.
KH2PO4 yog dab tsi?
KH2PO4 yog monopotassium phosphate. Nws tseem hu ua MKP, potassium dihydrogenphosphate, KDP, lossis monobasic potassium phosphate. Nws yog ib qho inorganic compound uas feem ntau siv los ua chiv nrog rau dipotassium phosphate. Peb qhov kev siv tseem ceeb ntawm KH2PO4 yog kev tsim cov chiv, ua cov khoom noj ntxiv hauv kev lag luam zaub mov thiab ua tus neeg sawv cev buffering. Tsis tas li ntawd, peb tuaj yeem pom tias cov ntsev no ua rau cocrystallization nrog dipotassium ntsev thiab nrog phosphoric acid. Txawm li cas los xij, peb tuaj yeem pom muaj ib qho crystals ntawm KH2PO4 uas yog paraelectric ntawm chav tsev kub. Lawv tuaj yeem ua ferroelectric ntawm qhov kub thiab txias. Hauv nws daim ntawv muag khoom, KH2PO4 yog cov hmoov dawb uas yog deliquescent.
Daim duab 01: Kev tshwm sim ntawm KH2PO4
KH2PO4 tuaj yeem muaj nyob hauv ntau cov qauv polymorphic. Nyob rau hauv chav tsev kub, KH2PO4 tshwm sim nyob rau hauv paraelectric siv lead ua daim ntawv muaj tetragonal symmetry. Ntawm qhov kub thiab txias, nws tuaj yeem hloov mus rau hauv ferroelectric siv lead ua cov ntaub ntawv uas muaj orthorhombic symmetry. Tsis tas li ntawd, cua sov cov khoom mus rau qhov kub thiab txias tuaj yeem ua rau tsim ntawm monoclinic KH2PO4. Tom qab cua sov ntxiv, cov tshuaj no tuaj yeem hloov mus rau hauv potassium metaphosphate KPO3 los ntawm kev decomposition ntawm KH2PO4.
Thaum xav txog kev tsim cov KH2PO4, peb tuaj yeem tsim nws los ntawm cov tshuaj tiv thaiv ntawm phosphoric acid ntawm potassium carbonate.
K2HPO4 yog dab tsi?
K2HPO4 yog dipotassium phosphate. Lwm lub npe rau cov tshuaj no yog dipotassium hydrogen orthophosphate thiab potassium phosphate dibasic. Nws yog ib qho inorganic compound uas muaj txiaj ntsig zoo hauv kev tsim cov chiv, ua zaub mov ntxiv thiab ua tus neeg sawv cev buffering. Cov khoom no zoo li cov khoom dawb lossis xim tsis muaj xim, uas yog dej-soluble.
Daim duab 02: Qhov tshwm sim ntawm K2HPO4
Ntawm kev lag luam nplai, peb tuaj yeem tsim K2HPO4 los ntawm ib nrab ntawm kev ua kom tsis zoo ntawm phosphoric acid siv ob qhov sib npaug ntawm cov poov tshuaj chloride compound.
Peb tuaj yeem siv K2HPO4 ua cov khoom noj ntxiv hauv kev coj ua ntawm cov khoom noj siv mis, cov dej haus qhuav, tshuaj ntxhia, thiab cov kab lis kev cai pib. Tsis tas li ntawd, nws tuaj yeem ua haujlwm ua emulsifier, stabilizer, thiab ua texturizer, tus neeg sawv cev buffering, chelating cov neeg ua haujlwm tshwj xeeb rau calcium hauv cov khoom noj mis nyuj, thiab lwm yam.
KH2PO4 thiab K2HPO4 yog dab tsi?
- KH2PO4 thiab K2HPO4 muaj txiaj ntsig zoo hauv kev tsim cov chiv.
- Ob leeg pom zoo li cov hmoov dawb uas yog deliquescent.
- Lawv yog dej-soluble.
KH2PO4 thiab K2HPO4 txawv yog dab tsi?
Cov ntsiab lus monobasic thiab dibasic hais txog cov poov tshuaj cations khi rau phosphate molecule. Qhov sib txawv tseem ceeb ntawm KH2PO4 thiab K2HPO4 yog tias KH2PO4 yog monobasic, yog li nws tuaj yeem tso cov poov tshuaj tsawg, thaum K2HPO4 yog dibasic, yog li nws tuaj yeem tso cov poov tshuaj ntau thaum siv hauv chiv. Ntxiv mus, monobasic KH2PO4 compound tuaj yeem siv tsuas yog ib qho hydrogen ion lossis proton los ntawm nws cov kev daws, whereas dibasic K2HPO4 compound muaj ob lub poov tshuaj ions uas tuaj yeem hloov mus rau ob hydrogen ions lossis protons.
Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm KH2PO4 thiab K2HPO4 hauv daim ntawv teev npe.
Summary – KH2PO4 vs K2HPO4
Cov ntsiab lus monobasic thiab dibasic yog hais txog tus naj npawb ntawm cov poov tshuaj cations khi rau phosphate molecule. Qhov sib txawv tseem ceeb ntawm KH2PO4 thiab K2HPO4 yog tias KH2PO4 yog monobasic thiab tuaj yeem tso cov poov tshuaj tsawg, thaum K2HPO4 yog dibasic thiab tuaj yeem tso tawm ntau cov poov tshuaj thaum siv chiv.
