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".

Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
Dab tsi cuam tshuam rau kev tshem cov choj ntsev muaj rau kev ua haujlwm ntawm txhua lub xov tooj ntawm tes electrochemical?
Yog tsis muaj ntsev choj, cov tshuaj nyob rau hauv lub anode compartment yuav ua tau zoo them thiab cov tshuaj nyob rau hauv lub cathode compartment yuav ua tsis zoo nqi, vim hais tias ntawm tus nqi imbalance, lub electrode cov tshuaj tiv thaiv yuav sai sai los mus rau ib tug nres, yog li ntawd nws yuav pab kom tswj tau qhov khiav. los ntawm electrons
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
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
