Tsis tas li ntawd, xim dab tsi yog CoCl4 2?

xiav

Tsis tas li ntawd, puas yog kev tsim ntawm Tetrachlorocobalt II complex ib qho exothermic lossis endothermic txheej txheem? Cov tsim ntawm tetrachlorocobalt tshuaj ( II ) yog ib txheej txheem exothermic vim cua sov yog ib yam khoom nyob rau hauv no tshuaj tiv thaiv.

Ib yam li ntawd, nws tau nug, 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.

Txoj kev twg yog qhov sib npaug hloov thaum HCl ntxiv?

Yog hais tias hydrochloric acid yog ntxiv mus rau kev sib npaug sib tov, ob qho tib si hydrogen ions (H +) thiab chloride ions (Cl -) ua ntxiv . Hydrogen ions nyob ntawm sab tes xis sab ntawm kev sib npaug , yog li ntawd cov kev sib npaug yuav ua haujlwm mus rau sab laug tes sab kom them rov qab, ua rau muaj ntau dua concentration ntawm reactants.
