Qhov sib txawv tseem ceeb ntawm liab thiab dawb phosphorus yog cov liab phosphorus tshwm li cov xim liab tsaus nti uas muaj cov phosphorus dawb tshwm sim raws li cov khoom siv pob tshab uas ua daj sai sai thaum raug teeb.

Phosphorus yog cov tshuaj lom neeg uas tshwm sim hauv ntau qhov sib txawv allotropes. Cov allotropes feem ntau yog cov ntawv liab thiab dawb, thiab cov no yog cov khoom sib txuas. Tsis tas li ntawd, thaum raug lub teeb, daim ntawv dawb hloov mus rau hauv daim ntawv liab. Txawm li cas los xij, muaj ntau qhov sib txawv ntawm ob qho allotropes. Cia peb tham ntxiv txog qhov sib txawv ntawm liab thiab dawb phosphorus.

Liab Phosphorus yog dab tsi?

Liab phosphorus yog ib qho allotrope ntawm phosphorus uas muaj xim liab tsaus. Nws yog qhov thib ob feem ntau allotrope ntawm phosphorus. Cov tshuaj no yog non-toxic thiab tsw. Ntxiv mus, nws yog chemically active. Tsis zoo li dawb phosphorus, nws tsis yog phosphorescent. Ntxiv rau qhov ntawd, daim ntawv no yog amorphous network.

Daim duab 01: Pom Liab Phosphorous

Ntxiv mus, qhov sib xyaw no muaj cov qauv polymeric. Nws pom tias yog ib qho piv txwv ntawm P4 units uas ib qho P-P daim ntawv cog lus tau tawg thiab ib qho nyiaj ntxiv muaj nyob nruab nrab ntawm ob P4 units. Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm kev kho cua sov phosphorous. Ntawd yog, cua sov cov phosphorous dawb mus txog 300 ° C ua rau qhov kev hloov pauv ntawm ob daim ntawv allotropic. Txawm li cas los xij, peb yuav tsum ua nws thaum tsis muaj huab cua. Los yog lwm yam, peb tuaj yeem nthuav tawm cov phosphorus dawb rau hnub ci. Qhov no kuj tsim cov liab allotrope. Ntxiv mus, nws tsis ignite nyob rau hauv huab cua ntawm kub hauv qab 240 ° C.

Daim ntawv thov:

  • Nyob hauv lub thawv sib tw los tsim hluav taws
  • Raws li cov khoom lag luam flare
  • Raws li cov khoom siv hauv cov pa luam yeeb
  • To create methamphetamine
  • siv tau raws li hluav taws kub retardant

Phosphorus yog dab tsi?

Dawb phosphorus yog ib qho allotrope ntawm phosphorus uas tshwm sim raws li cov khoom siv pob tshab. Cov tshuaj no muaj nyob rau hauv molecules; as P4 units. Cov molecules no muaj cov qauv tetrahedral. Cov qauv no ua rau nws lub nplhaib strain thiab instability. Muaj ob daim ntawv ua alpha thiab beta daim ntawv. Daim ntawv alpha yog lub xeev tus qauv.

Daim duab 02: Pom ntawm Dawb Phosphorous

Cov khoom siv quav ciab no sai sai ua daj thaum raug tshav ntuj. Yog li ntawd, qee zaum peb hu nws "daj phosphorus". Nws glows nyob rau hauv ib tug greenish tsos nyob rau hauv qhov tsaus ntuj nti (nyob rau hauv lub xub ntiag ntawm oxygen). Tsis tas li ntawd, nws yog tshuaj lom thiab kub heev, thiab kuj muaj tus kheej-igniting xwm. Peb tuaj yeem khaws cov khoom sib xyaw no hauv qab dej vim tias nws yog me ntsis soluble hauv dej. Peb tuaj yeem tsim cov allotrope no siv cov pob zeb phosphate; nyob rau ntawd peb sov lub pob zeb nyob rau hauv ib tug hluav taws xob los yog roj hluav taws xob rauv (nyob rau hauv lub xub ntiag ntawm carbon thiab silica). Qhov no evolving elemental phosphorus. Peb tuaj yeem sau cov phosphorus no hauv qab phosphoric acid. Ntxiv mus, qhov no allotrope tuaj yeem ua rau nws tus kheej ntawm qhov kub ntawm 50 ° C.

Daim ntawv thov:

  • Raws li riam phom (vim nws qhov hluav taws xob ntawm qhov kub qis heev)
  • Raws li ib qho ntxiv hauv napalm
  • Tau tsim liab phosphorus

Qhov txawv ntawm Liab thiab Dawb Phosphorus yog dab tsi?

Liab phosphorus yog ib qho allotrope ntawm phosphorus uas muaj xim liab tsaus. Nws tshwm sim raws li lub network polymeric. Qhov tseem ceeb, nws zoo li tsaus liab xim muaju. Tsis zoo li dawb allotrope, nws yog nontoxic. Ntxiv mus, nws ignites hauv huab cua ntawm qhov kub siab tshaj 240 ° C. Dawb phosphorus yog ib qho allotrope ntawm phosphorus uas tshwm sim raws li cov khoom siv pob tshab. Nws tshwm sim raws li P4 molecules. Cov tshuaj no tshwm sim raws li cov khoom siv waxy translucent uas sai sai ua daj thaum raug lub teeb. Nws yog tshuaj lom heev. Nyob rau hauv tas li ntawd, nws ignites nyob rau hauv cov huab cua ntawm tsawg kub xws li 50 ° C. Cov infographic hauv qab no nthuav tawm qhov sib txawv ntawm liab thiab dawb phosphorus hauv daim ntawv tabular.

Summary – Liab vs Dawb Phosphorus

Muaj ob qhov loj ntawm phosphorus li liab thiab dawb phosphorus. Qhov sib txawv tseem ceeb ntawm liab thiab dawb phosphorus yog cov liab phosphorus tshwm li cov xim liab tsaus nti thaum cov phosphorus dawb tshwm sim raws li cov khoom siv pob tshab uas ua daj sai sai thaum raug teeb.
