Lub hauv paus nyuaj yog electronegative heev thiab tsis tshua muaj polarizability. Piv txwv ntawm Hard Bases : F^-, OH^-, NH₃, N₂H₄, ROH, H₂O, SO₄²^-, PO₄³^- Lub hauv paus nyuaj react yooj yim dua los tsim cov tebchaw ruaj khov thiab cov complexes nrog nyuaj kua qaub.

Tsis tas li cov lus nug yog, cov acids nyuaj thiab cov hauv paus ua piv txwv yog dab tsi?

Hlau-ligand kev sib tshuam yog ib eg a Lewis kua qaub – puag kev sib tham. Lewis hauv paus tuaj yeem muab faib ua ob pawg: nyuaj bases muaj me me, kuj tsis muaj polarizable pub atoms (xws li N, O, thiab F), thiab.

Nyuaj thiab Mos Acids thiab Bases.

	Cov kua qaub	Bases
nyuaj	Al³⁺, Sc³⁺, Cr³⁺	CO₃²⁻
nyuaj	Ti⁴⁺	PO₄³⁻
mos	BF₃, Al₂Cl₆, CO₂,SO₃
mos	Cu⁺, Ag⁺, Aw⁺, Tl⁺, Hg₂²⁺	H⁻

Tsis tas li ntawd, vim li cas nyuaj acids nyiam cov hauv paus tawv? Txoj kev xav elaborates qhov ntawd nyuaj acids nyiam mus khi nrog nyuaj bases , thiab qhov tshwm sim adduct zoo li muaj ntau tus cwj pwm ionic hauv nws txoj kev sib txuas. Sib piv, mos acids nyiam mus khi nrog mos hauv paus , thiab lawv cov adducts yog ntau covalent nyob rau hauv qhov.

Ib sab saum toj no, puas yog oxygen lub hauv paus tawv lossis mos?

Qhov kev soj ntsuam no thaum kawg tau coj mus rau qhov kev faib tawm hu ua Hard and Soft Acids and Bases (HSAB). Hauv cov ntsiab lus, me me los yog ntau dua cov hlau ions raug hu ua hard acids. Lawv feem ntau yuav khi rau cov hauv paus tawv, uas feem ntau muaj me me pub atoms xws li oxygen lossis nitrogen.

Puas yog tooj liab yog ib qho nyuaj lossis soft acid?

Nyob rau hauv no milieu, lub hauv paus ntsiab lus ntawm nyuaj thiab cov kua qaub thiab cov hauv paus (HSAB) tau yog ib qho kev qhia zoo heev rau cov kws tshuaj inorganic. Tooj (i) tau muab faib ua ib mos cation.

Qhov twg yog lub hauv paus muaj zog nh3 lossis h2o?

Yog li NH3 muaj lub siab nyiam lees txais H + dua H2O (yog li ntawd H2O yuav txais cov proton thiab ua raws li lub hauv paus thiab NH3 yuav ua raws li cov kua qaub, tab sis peb paub tias nws yog lub hauv paus hauv H2O)

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?

Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai

Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?

Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no

Qhov twg yog lub hauv paus unit hauv SI?

SI system, tseem hu ua metric system, yog siv thoob ntiaj teb. Muaj xya chav nyob hauv SI system: lub ntsuas (m), kilogram (kg), qhov thib ob (s), kelvin (K), ampere (A), mole (mol), thiab candela ( cd)
