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 sib xyaw 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.

Tib neeg kuj nug, dab tsi yog hydrated ntsev muab piv txwv?

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

Tom qab ntawd, lo lus nug yog, qhov txawv ntawm hydrated ntsev thiab anhydrous ntsev yog dab tsi? 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".

Kuj tseem paub yog, hydrated ntsev tsim li cas?

Hydrates ntawm Ntsev . Thaum twg ntsev crystallize los ntawm cov kua dej aqueous, cov ions yuav khaws tau qee qhov ntawm hydrating dej molecules thiab daim ntawv khoom hydrates xws li Na2CO3·10H2O thiab CuSO4·5H2O. Ob qho tib si qhov loj ntawm ion thiab nws cov nqi tswj tau qhov twg hydration.

Yuav ua li cas rau hydrated ntsev thaum rhuab?

Thaum a hydrate ntsev Yog cua sov , cov qauv siv lead ua 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 cov khoom sib xyaw kuj tuaj yeem hloov pauv.
