Qhov sib txawv tseem ceeb ntawm hydrated ntsev thiab cov ntsev tsis muaj dej yog tias cov ntsev ntsev molecules txuas nrog rau cov dej molecules hos cov ntsev tsis muaj dej tsis txuas rau cov dej molecules. Yog tias peb sov cov dej ntsev, lawv tawm cov dej molecules li dej vapor.
Cov ntsev yog cov khoom sib xyaw uas muaj cov anions thiab cations hauv daim ntawv crystalline. Cov ntsev yog tsim los ntawm kev sib xyaw ntawm anion ntawm cov kua qaub thiab cov cation ntawm lub hauv paus. Muaj ob hom ntsev xws li hydrated ntsev thiab anhydrous ntsev. Cov tebchaw no txawv ntawm ib leeg raws li qhov muaj lossis tsis muaj dej molecules. Peb hu cov dej molecules "dej ntawm crystallization".
Hydrated S alt yog dab tsi?
Hydrated ntsev yog cov ntsev ntsev uas muaj cov dej molecules txuas nrog ntsev molecules. Ib qho tshuaj ntsev ntsev muaj qee tus lej ntawm cov dej molecules. Peb hu cov molecules no "dej ntawm crystallization" vim hais tias cov ntsev tebchaw muaj dej molecules incorporated rau hauv crystallization qauv ntawm ntsev. Cov dej molecules chemically khi nrog cov ntsev molecules. Cov dej molecules no ua rau cov duab ntawm cov muaju.
Daim duab 01: Hydrated Copper Sulfate
Cov ntsev ntsev no tsim thaum cov khoom ionic crystallize los ntawm cov kua dej. Thaum peb tshem tawm cov dej no los ntawm cov ntsev ntsev, nws dhau los ua anhydrous. Ib qho piv txwv ntawm hydrates ntsev yog tooj liab sulfate pentahydrate (CuSO 45H2O). Yog li ntawd, yog hais tias peb sov no compound, nws converts mus rau hauv anhydrous tooj liab sulfate. Qhov ntawd yog vim thaum cua sov, cov dej molecules evaporate.
Dab tsi yog Anhydrous ntsev ?
Anhydrous ntsev yog cov tebchaw uas tsis muaj dej molecules txuas nrog ntsev molecules. Peb siv lo lus no feem ntau thaum dej ntawm crystallization tshem tawm los ntawm hydrated ntsev. Yog li ntawd, lo lus anhydrous yog hais txog ntsev qhuav.
Daim duab 02: Anhydrous Copper Sulfate hloov mus rau xim xiav thaum Hydrated
Piv txwv li, anhydrous sodium sulfate tsis muaj dej. Yog li ntawd, peb tuaj yeem siv nws ua cov khoom ziab vim nws tuaj yeem nqus dej thiab hloov mus rau hauv daim ntawv hydrated.
Dab tsi yog qhov txawv ntawm Hydrated S alt thiab Anhydrous ntsev?
Hydrated ntsev yog cov ntsev ntsev uas muaj cov dej molecules txuas nrog ntsev molecules. Cov tshuaj no muaj cov dej ntawm crystallization. Yog tias peb ua kom sov cov ntsiab lus no, lawv tawm cov dej molecules li dej vapor. Anhydrous ntsev yog cov sib xyaw uas tsis muaj cov dej molecules txuas nrog cov ntsev molecules. Cov tebchaw no tsis muaj dej molecules hauv cov ntsev ntsev.
Summary – Hydrated S alt vs Anhydrous S alt
Ntshav yog cov derivatives ntawm kev sib xyaw ntawm cov kua qaub thiab cov hauv paus. Muaj ob hom ntsev xws li hydrated ntsev thiab anhydrous ntsev. Qhov txawv ntawm hydrated ntsev thiab anhydrous ntsev yog tias hydrated ntsev molecules yog txuas nrog dej molecules whereas anhydrous ntsev molecules tsis txuas rau tej dej molecules.
