Lithium yog qhov me me tshaj plaws ntawm cov hlau alkali. Li no, Li+ ion tuaj yeem polarize dej molecules yooj yim dua li lwm cov alkali hlau. … Li no, lithium ntsev xws li trihydrated lithium chloride (LiC1. 3H20) feem ntau hydrated.
Vim li cas cov ntsev lithium thiaj li muaj dej ntau dua?
Lithium paub tias muaj qhov me me tshaj plaws ntawm tag nrho cov alkali hlau. Qhov no yog qhov laj thawj tseem ceeb vim li cas Li + ion muaj peev xwm ua polarize dej molecules yooj yim dua thaum pivrau lwm cov hlau alkali.
Puas lithium muab cov ntsev hydrated?
The s-Block Elements. Dab tsi ntawm cov alkali hlau hauv qab no muab hydrated ntsev? Li. Txij li qhov loj ntawm Li+ yog qhov tsawg tshaj plaws ntawm cov alkali hlau ions, yog li nws muaj qhov hnyav tshaj plaws thiab yog li nyiam cov dej molecules ntau dua li lwm yam alkali hlau cation.
Vim li cas qee cov ntsev hydrated?
1)Vim li cas ntsev thiaj li hu ua hydrated: Cov ntsev hu ua hydrated s alts vim muaj ib los yog ntau tshaj cov tshuaj ua ke dej molecule Qhov no hu ua dej crystallization. Nws qhia cov naj npawb ntawm cov dej molecules uas yog tshuaj ua ke nrog cov ntsev hauv nws lub xeev crystalline.
Lub ntsiab lus twg muab cov ntsev hydrated?
Ntawm cov hlau alkali, Li yog qhov me tshaj plaws. Tsis tas li ntawd, nws muaj cov nqi siab tshaj plaws thiab lub zog polarizing siab tshaj plaws. Yog li, nws nyiam cov dej molecules ntau dua li lwm cov alkali hlau. Yog li ntawd, nws tsim hydrated ntsev xws li LiCl.
