Cov lus piav qhia (nrog rau kev sib npaug tshuaj lom neeg tseem ceeb):

Co (H2O)62+ complex yog liab, thiab 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.

Thiab cov lus nug yog, dab tsi xim yog cocl42?

xiav

Ib yam li ntawd, ntxiv chloride ions ua dab tsi rau aqua cobalt complex? Qhov sib ntxiv ntawm chloride ion thawb lub equilibrium mus rau txoj cai nyiam tsim cov xiav tetrachloro cobalt hom khoom. Ntxiv dej rau qhov kev daws teeb meem thawb qhov sib npaug mus rau sab laug nyiam lub paj yeeb hexaaqua cobalt hom reactant.

Raws li, vim li cas CoCl2 hloov xim thaum rhuab?

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.

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.
