Qhov sib txawv tseem ceeb ntawm ib qho kev hloov pauv thiab ob qhov kev hloov pauv hloov pauv yog tias, hauv ib qho kev hloov pauv hloov pauv, ib hom tshuaj hloov pauv ib feem ntawm lwm hom tshuaj thaum, hauv ob qhov kev hloov pauv, kev pauv ntawm ob hom ionic ntawm ob lub molecules tshwm sim.
Kev hloov pauv ib zaug thiab kev hloov pauv ob zaug yog cov tshuaj lom neeg tseem ceeb uas cuam tshuam txog kev tsim cov ntawv cog lus thiab kev sib tsoo. Yog li, nws yog ib qho tseem ceeb kom paub qhov txawv qhov txawv ntawm ib qho kev hloov pauv thiab ob qhov kev hloov pauv hloov.
Kev Tawm Tsam Ib Leeg Yog Dab Tsi?
Ib qho kev hloov pauv ib leeg yog ib hom tshuaj tiv thaiv uas ib hom tshuaj hloov ib feem ntawm lwm hom tshuaj. Rau hom tshuaj tiv thaiv no tshwm sim, yuav tsum muaj cov kab mob reactive uas tuaj yeem hloov pauv ib feem ntawm cov molecule (xws li pab pawg ua haujlwm). Feem ntau, hom reactive yog cation, anion lossis hlau. Cov qauv dav dav rau hom kev tawm tsam no yog raws li hauv qab no:
A-B + C ⟶ A + B-C
Ntawm no, B yog ib feem ntawm AB molecule, thiab nws tau hloov los ntawm ib hom reactive C. Tom qab ntawd, BC molecule yog tsim. Peb tuaj yeem kwv yees qhov tshwm sim ntawm qhov kev hloov pauv hloov pauv los ntawm kev saib cov reactivity series. Ntawm no, cov ntsiab lus tshuaj nyob rau sab saum toj ntawm koob tuaj yeem hloov cov tshuaj lom neeg hauv qab ntawm koob. Cia peb xav txog ib qho piv txwv;
Zn + 2HCl ⟶ ZnCl2 + H2
Hauv qhov piv txwv saum toj no, Zn yog nyob rau thaj tsam sab saud ntawm cov reactivity series thaum H nyob hauv cheeb tsam qis; Yog li ntawd, Zn tuaj yeem hloov H hauv HCl thiab tsim ZnCl2.
Dab tsi yog qhov kev hloov pauv hloov pauv?
Ob qhov kev hloov pauv hloov pauv yog hom tshuaj lom neeg uas muaj kev sib pauv ntawm ob hom ionic ntawm ob lub molecules tshwm sim. Cov qauv dav dav yog raws li hauv qab no:
A-B + C-D ⟶ A-C + B-D
Daim duab 01: nag lossis daus ntawm nyiaj ntawm tooj liab
Daim ntawv cog lus uas tawg thiab tsim thaum lub sijhawm cov tshuaj tiv thaiv no tuaj yeem yog ionic lossis covalent bonds. Qee qhov piv txwv ntawm cov tshuaj tiv thaiv no muaj xws li nag lossis daus, tshuaj tiv thaiv acid-puag, alkylation, thiab lwm yam.
Qhov txawv ntawm Ib Qhov Kev Tawm Tsam Ib Leeg thiab Kev Tawm Tsam Ob Qhov Kev Tawm Tsam yog dab tsi?
Ib qho thiab ob qhov kev hloov pauv hloov pauv yog ob hom tshuaj lom neeg cov tshuaj tiv thaiv uas tseem ceeb hauv kev cais cov khoom xav tau los ntawm kev daws teeb meem. Qhov sib txawv tseem ceeb ntawm ib qho kev hloov pauv thiab ob qhov kev hloov pauv hloov pauv yog tias nyob rau hauv ib qho kev hloov pauv hloov pauv, ib hom tshuaj hloov ib feem ntawm lwm hom tshuaj lom neeg thaum, nyob rau hauv ob qhov kev hloov pauv, kev sib pauv ntawm ob hom ionic ntawm ob lub molecules tshwm sim. Ib qho kev hloov pauv hloov pauv yuav tsum muaj cov kab mob reactive uas tuaj yeem hloov cov pab pawg ua haujlwm thaum ob qhov kev hloov pauv hloov yuav tsum muaj cov ions sib pauv. Yog li, qhov no yog lwm qhov sib txawv ntawm ib qho kev hloov pauv thiab ob qhov kev hloov pauv hloov.
Ntxiv mus, Zn hloov H hauv HCl thiab tsim ZnCl 2 yog ib qho piv txwv ntawm ib qho kev hloov pauv, thaum nag lossis daus tshwm sim, acid-base tshua, alkylation, thiab lwm yam. ntawm ob qhov kev hloov pauv hloov.
Summary – Ib qho Kev Tawm Tsam vs Ob Qhov Kev Tawm Tsam Tawm
Ib qho thiab ob qhov kev hloov pauv hloov pauv yog ob hom tshuaj lom neeg cov tshuaj tiv thaiv uas tseem ceeb hauv kev cais cov khoom xav tau los ntawm kev daws teeb meem. Qhov sib txawv tseem ceeb ntawm ib qho kev hloov pauv thiab ob qhov kev hloov pauv hloov pauv yog tias nyob rau hauv ib qho kev hloov pauv hloov pauv, ib hom tshuaj hloov pauv ib feem ntawm lwm hom tshuaj lom neeg thaum, nyob rau hauv ob qhov kev hloov pauv, kev pauv ntawm ob hom ionic ntawm ob lub molecules tshwm sim.
