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.

Dab tsi yog lub npe ntsev tsim los ntawm neutralization ntawm hydrochloric acid thiab sodium hydroxide?
Kev piav qhia: Cov tshuaj tiv thaiv ntawm sodium hydroxide (NaOH) thiab hydrochloric acid (HCl) yog cov tshuaj tiv thaiv nruab nrab uas ua rau muaj ntsev, sodium chloride (NaCl), thiab dej (H2O). Nws yog ib qho tshuaj tiv thaiv exothermic
Yuav ua li cas thaum lub hydrated ntsev yog rhuab?
Thaum lub hydrate ntsev yog rhuab, 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 tseem tuaj yeem hloov pauv
Puas yog NaHS yog ntsev ntsev?
Acid ntsev Cov ntsev tseem muaj hydrogen atom los ntawm cov kua qaub uas tuaj yeem hloov tau los ntawm cov hlau ions ntxiv. Piv txwv xws li: NaHSO4, NaHCO3 thiab NaHS 3. Basic ntsev Cov ntsev muaj cov hydroxides ua ke nrog cov hlau ions thiab cov ions tsis zoo los ntawm cov kua qaub
Puas yog NaH2PO3 yog ntsev ntsev?
Na2HPO3 yog tsim thaum ob lub acidic hydrogens hloov los ntawm sodium. Nws tsis muaj acidic hydrogen. Yog li, nws yog ib txwm sodium ntsev ntawm phosphorus acid. Tab sis NaH2PO3 yog cov ntsev ntsev vim nws tseem muaj ib qho acidic lossis hloov tau hydrogen hauv nws cov muaj pes tsawg leeg
Dab tsi yog cov mis rau hydrated ntsev?
1 Inorganic ntsev hydrates li PCMs. Ntsev hydrates suav nrog ib pawg tseem ceeb ntawm PCMs. Inorganic ntsev hydrate (hydrated ntsev los yog hydrate) yog ib tug 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. Cov mis mos ntawm hydrated ntsev yog MxNy
