Tooj (i) tau muab faib ua ib mos cation. Txawm li cas los xij, muaj peev xwm ntawm tooj liab (i) khi nyuaj los yog mos pub dawb thiab qhov sib txawv reactivities nthuav tawm los ntawm tooj liab (i) complexes tau tsa ib co lus nug txog qhov xwm ntawm tooj liab (i).
Yog li ntawd, tooj liab yog tawv los yog mos?
Ntshiab tooj liab yog mos thiab tuaj yeem kos rau hauv cov hlau lossis hammered rau hauv cov duab uas xav tau. Cov txheej txheem shaping no ua rau cov hlau ua nyuaj vim hais tias cov pob zeb loj loj tau tawg mus rau hauv cov nplej me me, ntxiv dag zog rau cov hlau. Yog tias tooj liab yog tom qab rhuab (annealed), nws tuaj yeem ua tau mos dua.
Tsis tas li, CN puas yog lub hauv paus tawv lossis mos? mos bases muaj cov loj, kuj polarizable pub atoms (xws li P, S, thiab Cl).
Nyuaj thiab Mos Acids thiab Bases.
| Cov kua qaub | Bases | |
|---|---|---|
| nyuaj | Ti4+ | PO43− |
| mos | BF3, Al2Cl6, CO2,SO3 | |
| Cu+, Ag+, Aw+, Tl+, Hg22+ | H− | |
| Pd2+, Pt2+, Hg2+ | CN−, SCN−, kuv−, RS− |
Ua raws li qhov no hauv kev txiav txim siab, zinc puas yog ib qho nyuaj lossis mos acid?
Ib kua qaub los yog lub hauv paus tej zaum yuav nyuaj los yog mos thiab kuj yuav tsis muaj zog lossis muaj zog. Zinc ion yog ib tug muaj zog Lewis kua qaub , thiab oxide ion yog lub zog Lewis puag.
Dab tsi yog qhov nyuaj acid hauv chemistry?
Kev txhais ntawm Hard Acid . Cov kua qaub nyuaj yog Lewis kua qaub uas tsuas yog weakly polarizable. Lwm yam yog kwv yees li sib npaug: nyuaj acids teb sai nrog nyuaj bases thiab tsim kom muaj kev sib raug zoo nrog lawv. mos kua qaub hnov mob sai dua nrog cov hauv paus mos thiab tsim kom muaj kev sib raug zoo nrog lawv.

Puas yog tooj liab oxide soluble hauv sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Puas yog tooj liab khov lossis aqueous?
Hauv alchemy, lub cim rau tooj liab kuj yog lub cim rau lub ntiaj teb Venus. Cov ntsiab lus tuaj yeem raug cais raws li lawv lub cev lub xeev (States of Matter) e.g. gas, khoom los yog kua. Cov khoom no yog ib qho khoom. Copper yog cais raws li 'Transition Hlau' uas nyob hauv Pawg 3 - 12 ntawm Lub Sij Hawm Lub Sij Hawm
Puas yog tooj liab reacts nrog sulfuric acid?
Tooj liab tsis hnov mob nrog dilute sulfuric acid vim nws qhov txo qis dua qhov muaj peev xwm ntawm hydrogen. Tooj liab tsis hloov hydrogen los ntawm cov tsis-oxidising acids xws li HCl los yog dilute H2SO4. Yog li, thaum tooj liab rhuab nrog conc. H2SO4, cov tshuaj tiv thaiv redox tshwm sim thiab cov kua qaub raug txo kom sulfur dioxide
Dab tsi yog qhov sib npaug ntawm tooj liab oxide thiab sulfuric acid?
Txhawm rau sib npaug CuO + H2SO4 = CuSO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug. Thaum koj paub ntau npaum li cas ntawm txhua hom atom koj tuaj yeem hloov pauv cov coefficients (tus lej nyob rau hauv pem hauv ntej ntawm atoms lossis cov tebchaw) kom sib npaug ntawm qhov sib npaug rau tooj liab (II) oxide + Sulfuric acid
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
