Phosphorus vs Phosphate

Lub voj voog phosphorus yog lub voj voog biogeochemical, uas piav qhia txog qhov sib txawv ntawm cov phosphorus ncig hauv lub ntiaj teb. Nws tsuas yog txwv rau lithosphere, vim tias phosphorus tsis muaj theem gaseous. Phosphorus feem ntau pom zoo li phosphates, khaws cia hauv av, pob txha, tsiaj txhu thiab cov nroj tsuag lub cev thiab hauv cov dej.

Phosphorus yog 15 lub ntsiab lus nyob rau hauv lub sij hawm nrog lub cim P. Nws kuj yog nyob rau hauv pawg 15 nrog rau nitrogen thiab muaj ib tug molecular hnyav ntawm 31 g mol^-1 Cov electron configuration ntawm phosphorus yog 1s²2s²2⁶3s² 3p^{3Nws yog ib qho atom multivalent thiab tuaj yeem tsim +3, +5 cations. Phosphorus muaj ob peb isotopes, tab sis P-31 muaj ntau nrog 100% ntau. P-32 thiab P-33 isotopes yog cov xov tooj cua, thiab tuaj yeem tso tawm cov beta ntshiab. Phosphorus reactive heev, yog li ntawd, tsis tuaj yeem tshwm sim raws li ib qho atom. Muaj ob hom loj ntawm phosphorus tam sim no nyob rau hauv cov xwm li dawb phosphorus thiab liab phosphorus. Dawb phosphorus muaj plaub P atoms teem rau hauv tetrahedral geometry. Dawb phosphorus yog xim daj daj ntseg pob tshab. Nws yog heev reactive raws li ib tug heev toxic. Liab phosphorus muaj nyob ua ib lub polymer thiab thaum cua sov dawb phosphorus, qhov no tuaj yeem tau. Lwm yam tshaj li dawb thiab liab phosphorus, muaj lwm yam, hu ua dub phosphorus thiab nws muaj ib tug qauv zoo li graphite.}

Phosphate

Phosphate yog hom tsis muaj tshuaj lom neeg ntawm phosphorus, uas muaj nyob hauv ib puag ncig ntuj. Lawv muaj nyob li deposits / pob zeb thiab cov no yog mined kom tau phosphorous xav tau. Ib qho phosphorus atom yog sib txuas nrog plaub oxygens los ua ib tug -3 polyatomic anion. Vim yog ib daim ntawv cog lus thiab ob daim ntawv cog lus, ntawm P thiab O, phosphorus muaj +5 oxidation xeev nyob rau hauv no. Nws muaj tetrahedral geometry. Hauv qab no yog cov qauv ntawm phosphate anion.

PO₄^3-

Phosphate anion tuaj yeem ua ke nrog cov cations sib txawv los tsim ntau cov ionic compounds. Thaum muaj peb hydrogen atoms txuas nrog, nws yog hu ua phosphoric acid. Phosphorus yog cov ntxhia ntau hauv lub cev, tshwj xeeb tshaj yog phosphates. Piv txwv li, muaj phosphate pawg hauv DNA, RNA, ATP, phospholipids, hauv cov pob txha thiab lwm yam. Cov phosphate qis hauv cov pob txha thiab cov ntshav yuav ua rau ntau yam kab mob rau tib neeg. Nws yog ib qho tseem ceeb kom suav nrog cov phosphate hauv peb cov zaub mov. Phosphorus tuaj yeem coj mus rau hauv peb lub cev li phosphates los ntawm cov khoom noj siv mis, ntses, nqaij, qe, nplej, thiab lwm yam.

Phosphorus kuj yog ib qho tseem ceeb macro ntsiab rau cov nroj tsuag. Yog li ntawd, chiv muaj phosphates loj. Txawm li cas los xij, yog tias cov phosphates no tau ntxuav tawm thiab khaws cia hauv dej, lawv tuaj yeem ua rau dej paug. Cov mob no yog hu ua eutrophication. Yuav ua li cas tshwm sim nyob rau hauv cov ntaub ntawv no yog, thaum muaj ib tug siab cov ntsiab lus nyob rau hauv dej lub cev phytoplankton yuav loj hlob sai heev vim hais tias lawv kuj xav tau cov as-ham xws li phosphates rau lawv txoj kev loj hlob. Thaum qhov no tshwm sim, cov pa oxygen yaj hauv dej yuav nqus los ntawm phytoplanktons loj, qhov twg lwm yam kab mob yuav tuag yam tsis muaj oxygen.

Qhov txawv ntawm Phosphorus thiab Phosphate yog dab tsi?

– Phosphorus yog ib qho atom thiab phosphate yog polyatomic anion.

– Phosphorus tsis ruaj khov raws li cov khoom, tab sis phosphate ruaj khov.

– Phosphorus muaj peev xwm tsim cations, tab sis phosphate yog anion.

– Peb muab phosphorus rau hauv peb lub cev hauv daim ntawv phosphates.
