Cov lus piav qhia (nrog rau kev sib npaug tshuaj lom neeg tseem ceeb):
Co (H2O)62+ complex yog liab , and CoCl42- complex yog xiav . Cov tshuaj tiv thaiv no yog endothermic raws li sau tseg, yog li ntxiv cov cua sov ua rau qhov sib npaug tsis tu ncua hloov mus rau sab xis. Qhov no, sib piv, ua rau kev daws teeb meem xiav.
Ib yam li ntawd, puas yog cov tshuaj tiv thaiv pem hauv ntej hauv CoCl4 2 ion?
2 + yog liab hauv cov kua dej thiab TxC4 2 - yog xiav. Cov pem hauv ntej cov tshuaj tiv thaiv yog exothermic. Qhov sib npaug ntawm ob hom tuaj yeem cuam tshuam los ntawm (i) ntxiv Cl- ions los yog dej los yog (ii) hloov qhov kub thiab txias. Hauv ob qhov xwm txheej, qhov kev hloov pauv uas tshwm sim yog raws li kev kwv yees los ntawm Le Chatelier's Principple.
Ib yam li ntawd, vim li cas CoCl2 hloov xim thaum cua sov? Qhov no txhais tau tias thaum twg kub yog ntxiv, i.e. kev daws teeb meem yog ua cua sov , lub equilibrium yuav hloov nyob rau hauv cov kev taw qhia ntawm cov khoom. Qhov kev hloov pauv hauv qhov sib npaug yuav tig cov tshuaj xiav, lub xim CoCl2-4 ion.
Tsis tas li ntawd, cov xim kub CoCl2 yog dab tsi?
liab
Puas yog Cobalt equilibrium exothermic lossis endothermic?
Piav raws li kev soj ntsuam yog tias cov tshuaj tiv thaiv yog exothermic lossis endothermic. Cov tshuaj tiv thaiv yog endothermic. Thaum tshav kub yog siv cov tshuaj tiv thaiv hloov mus rau sab xis. Qhov no yog pom tseeb raws li cov xim hloov ntawm liab dawb mus rau tsaus xiav qhia tau hais tias tsim ntawm Cobalt (II) chloride ions.

Ua kom sov Tones Qhov zoo tshaj plaws sov xim palettes rau knotty ntoo thuv siv tones ntawm daj ochre, burnt txiv kab ntxwv los yog cib liab. Cov tones sov tuaj yeem tinted nrog dawb thaum chav tsev xav tau cov xim sib dua. Cov xim no txuas lub ntuj sov ntawm cov ntoo tones, ntxiv kev nplua nuj thiab kev muaj sia nyob rau qhov chaw
