1 Inorganic ntsev hydrates li PCMs. Ntsev hydrates suav nrog ib pawg tseem ceeb ntawm PCMs. Ib qho inorganic ntsev hydrate ( hydrated ntsev los yog hydrate ) yog ib qho ionic compound nyob rau hauv uas ib tug xov tooj ntawm cov dej molecules yog attracted los ntawm cov ions thiab yog li ntawd nyob rau hauv nws siv lead ua lattice. Tus general qauv ntawm a hydrated ntsev yog MxNy

Ntawm no, hydrated ntsev muab piv txwv li cas?

Lwm cov piv txwv ntawm hydrates yog Glauber's ntsev ( sodium sulfate decahydrate, Na2YOG4∙10 H2O); ntxuav dej qab zib ( sodium carbonate decahydrate, Na2CO3∙10 H2O); borax ( sodium tetraborate decahydrate, Na2B4O7∙10 H2O); tus sulfates hu ua vitriols (piv txwv li, Epsom ntsev, MgSO4∙7 H2O); thiab cov ntsev ob lub npe hu ua alums (M+2

Kuj Paub, koj ua li cas pom cov feem pua ntawm cov dej hauv cov ntsev ntsev? Theoretical (qhov tseeb) hydration feem pua ( feem pua dej ) tuaj yeem yog xam los ntawm qauv ntawm hydrate los ntawm kev faib qhov loj ntawm dej nyob rau hauv ib tug mole hydrate los ntawm molar loj ntawm lub hydrate thiab muab faib los ntawm 100.

Hais txog qhov no, dab tsi yog hydrated ntsev hauv chemistry?

A hydrated ntsev yog crystalline ntsev molecule uas yog xoob txuas mus rau qee yam ntawm cov dej molecules. Ntsev yog tsim thaum cov kua qaub anion thiab lub hauv paus cation raug ua ke los tsim cov kua qaub-base molecule. Hauv ib hydrated ntsev , cov dej molecules yog incorporated rau hauv lub crystalline qauv ntawm lub ntsev.

Dab tsi yog qhov txawv ntawm hydrated ntsev thiab anhydrous ntsev?

Qhov sib txawv ntawm Hydrated ntsev thiab Anhydrous ntsev . Tus yuam sij Qhov sib txawv ntawm hydrated ntsev thiab anhydrous ntsev yog tus hydrated ntsev molecules yog txuas nrog dej molecules whereas lub anhydrous ntsev Cov molecules tsis txuas rau ib qho dej molecules. Peb hu cov dej molecules "dej ntawm crystallization".
