Thaum a 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 tuaj yeem hloov pauv.

Ib yam li ntawd, tib neeg nug, dab tsi yog hydrated ntsev?

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.

Tsis tas li ntawd, yuav ua li cas thaum lub hydrated ntsev dissolves hauv dej? Peb yuav xub xyuas cov txheej txheem ntawd tshwm sim thaum muaj ionic compound xws li rooj ntsev (sodium chloride) dissolves nyob rau hauv dej . Dej molecules txav mus tas li vim lawv lub zog kinetic. Thaum ib tug crystal ntawm sodium chloride muab tso rau hauv dej , cov cov dej cov molecules sib tsoo nrog cov siv lead ua lattice.

Yog li ntawd, 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

Yuav ua li cas hydrated ntsev tsim?

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.
