Fe2+, aka ferrous, yog daj ntseg ntsuab thiab puv violet thaum ntxiv rau dej. Fe3+, aka ferric, yog daj-xim av hauv kev daws.
Ib yam li ntawd, koj tuaj yeem nug, Xim yog fe3+?
Ion Xim
| ion | xim |
|---|---|
| Al+3 | tsis muaj xim |
| Cr+3 | ntsuab |
| Fe+2 | txiv kab ntxwv liab |
| Fe+3 | daj ntsuab |
Tsis tas li ntawd, qhov 3+ hauv fe3+ qhia li cas? Hauv chemistry, hlau ( III ) hais txog lub ntsiab hlau hauv nws + 3 oxidation xeev. Nyob rau hauv ionic compounds (salts), xws li ib tug atom yuav tshwm sim raws li ib tug cais cation (positive ion) denoted los ntawm Fe3+ . 3 . Lub adjective "ferrous" yog siv es tsis txhob hlau (II) ntsev, muaj cov cation Fe2+.
Ib sab saum toj, Dab tsi yog xim hlau 3+?
Txheeb xyuas qhov hloov pauv hlau ions
| Hlau ion | Xim |
|---|---|
| Hlau (II), Fe 2 + | Ntsuab - puv txiv kab ntxwv-xim av thaum sawv ntsug |
| Hlau (III), Fe 3 + | Txiv kab ntxwv-xim av |
| Tooj (II), Cu 2 + | Xiav |
Vim li cas Cu + tsis Coloured?
Cov xim Kev hloov pauv cov ntsiab lus yog vim muaj qhov tsis sib xws ntawm electrons. ua + yog xim tsis muaj xim raws li nws qhov kev teeb tsa sab nraud yog 3d10 yog li muaj tsis muaj unpaired electrons uas ua rau lub xim.

Dab tsi yog xim ntawm phenol liab ntawm acid pH thiab ntawm alkaline pH? daj ntawm acid pH, ci liab ntawm alkaline pH. Phenol liab yog liab los yog txiv kab ntxwv nyob nruab nrab pH
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 xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
