Yog ntsev molecule khi rau cov dej molecules, nws yog ntsev ntsev. Hauv lwm lo lus, hydrated ntsev yog ntsev molecule uas yog lankly txuas rau qee yam dej molecules. Cov ntsev feem ntau yog cov muaju nyob rau hauv lub xeev hydrated, txhais tau hais tias ib qho kev faib ua feem ntawm cov dej yog txuas nrog cov qauv siv lead ua.
Yuav ua li cas thaum ntsev hydrated?
Ib hydrated ntsev yog crystalline ntsev molecule uas yog xoob txuas mus rau ib co dej molecules. Ntsev yog tsim thaum an acid's anion thiab lub hauv paus cation tau ua ke los tsim cov kua qaub-puag molecule. … Hauv cov dej ntsev, cov dej molecules tau muab tso rau hauv cov qauv crystalline ntawm cov ntsev.
Thaum cov ntsev hydrated rhuab nws yuav ua ntej?
Thaum cov ntsev hydrate rhuab, lub crystal qauv ntawm cov compound yuav hloov. Ntau hydrates muab loj, zoo tsim muaju. Lawv tuaj yeem tawg thiab tsim cov hmoov raws li cov dej ntawm cov dej ntws tawm. Cov xim ntawm qhov sib xyaw kuj tseem tuaj yeem hloov pauv.
piv txwv ntawm cov ntsev ntsev yog dab tsi?
Ib ntsev uas muaj ntau cov dej molecules txuam nrog cov ions hauv nws cov qauv crystalline hu ua Hydrated ntsev. Piv txwv ntawm hydrated ntsev yog: Ntxuav Soda-Na 2 CO 3. 10H2O.
Yuav ua li cas ua ntsev ntsev?
Kev npaj ntawm ionic hydrates yog ua tiav los ntawm plaub txoj kev: (i) qeeb evaporation ntawm covCov kuab tshuaj los ntawm qhov ze saturated tov ntawm qhov pib hydrate ntawm qhov kub thiab txias nyob rau hauv qhov chaw ruaj khov ntawm qhov xav tau hydrate, (ii) crystallization nyob rau hauv qhov kub thiab txias ntawm lub hom phiaj hydrate los ntawm saturated …
