Dissolved hlau yog tam sim no raws li Fe (OH)2+ (aq) nyob rau hauv acidic thiab nruab nrab, oxygen-nplua nuj tej yam kev mob. Nyob rau hauv cov xwm txheej tsis zoo oxygen nws feem ntau tshwm sim li binary hlau. Hlau yog ib feem ntawm ntau cov organic thiab inorganic chelation complexes uas feem ntau dej soluble.
Tsis tas li ntawd, hom hlau twg yog soluble?
Hlau muaj nyob rau hauv ob lub xeev oxidation: ferrous cation (Fe2+) thiab ferric cation (Fe3+). Tsis yog hlau nyob rau hauv cov zaub mov yog tsuas yog nyob rau hauv lub xeev ferric, uas yog lub insoluble daim ntawv ntawm hlau , thiab yuav tsum tau txo mus rau ferrous cation rau nqus 7.
Tom qab ntawd, lo lus nug yog, uas yog ntau dua soluble fe2 lossis fe3? Re: Fe 2+ piv rau Fe3+ solubility Tej zaum nws muaj qee yam ua rau acidity txij li Fe + 3 yog ntau acidic tshaj Fe + 2, thiab Fe + 3 ntsev tsuas yog soluble qis dua ib qho pH (dej pH ntawm 7 tshaj qhov pH) thaum Fe + 2 yog ntau yooj yim thiab yog soluble qis dua pH.
Hais txog qhov no, puas Hlau yaj hauv dej?
Hlau tsis yog yaj nkag hauv dej , txawm hais tias nws yuav twv yuav raug xeb sai dua (raws li koj tau pom los ntawm kev paub dhau los). Txawm li cas los xij, hydrochloric acid, tuaj yeem yaj hlau , thiab ib tug ntau concentrated tov yuav yaj nws sai dua.
Puas yog ferrous hlau soluble?
Cov hlau yuav nyob rau hauv ib qho ntawm ob lub xeev oxidation: ferrous muaj tus nqi +2, lossis ferric muaj tus nqi +3. Hlau hlau yog soluble hauv dej ntawm ib qho pH.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Dab tsi yog 4 yam khoom ntawm cov hlau tsis muaj hlau?
Summary of Common Properties High ionization energies. High electronegativities. Cov thermal conductors tsis zoo. Cov hluav taws xob tsis zoo. Cov khoom tawg yooj yim - tsis tuaj yeem ua los yog ductile. Me me los yog tsis muaj xim hlau luster. Tau txais electrons yooj yim. Npub, tsis yog xim hlau-ci, txawm tias lawv yuav muaj xim
Dab tsi ntawm cov hlau hauv qab no yog alkaline ntiaj teb hlau?
Cov tswv cuab ntawm alkaline ntiaj teb hlau muaj xws li: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) thiab radium (Ra). Ib yam li txhua tsev neeg, cov ntsiab lus no qhia qhov zoo. Txawm hais tias tsis zoo li cov hlau alkali, tsev neeg no paub yuav ua li cas ua cov ntawv cog lus yooj yim heev
