Ionic compounds yaj hauv dej yog lub zog muab tawm thaum cov ions cuam tshuam nrog dej molecules them rau lub zog xav tau los rhuav tshem cov ionic bonds hauv cov khoomthiab lub zog yuav tsum tau ua. cais cov dej molecules kom cov ions tuaj yeem nkag mus rau hauv cov tshuaj.
Puas cov ionic feem ntau yaj hauv dej?
Dej feem ntau dissolves ntau ionic compounds thiab polar molecules. Nonpolar molecules xws li cov pom nyob rau hauv roj los yog roj tsis yaj nyob rau hauv dej. Peb yuav xub tshuaj xyuas cov txheej txheem uas tshwm sim thaum muaj ionic compound xws li cov ntsev ntsev (sodium chloride) yaj hauv dej.
Yuav ua li cas ionic compound yuav tsum yaj nyob rau hauv dej?
Polar compounds nyiam yaj hauv dej, thiab peb tuaj yeem txuas qhov dav dav mus rau feem ntau cov polar compounds ntawm tag nrho cov-ionic compounds. Table ntsev, lossis sodium chloride (NaCl), feem ntau ionic compound, yog soluble hauv dej (360 g / L).
Yuav ua li cas thaum cov tshuaj ionic soluble yaj hauv dej?
Thaum ionic compounds dissolve nyob rau hauv dej,
cov ions nyob rau hauv cov khoom sib cais thiab disperse uniformly thoob plaws hauv cov tshuaj vim hais tias dej molecules nyob ib puag ncig thiab daws cov ions , txo cov electrostatic zog ntawm lawv.. Cov txheej txheem no sawv cev rau kev hloov ntawm lub cev hu ua dissociation.
Vim li cas ionic compounds dissolve yooj yim?
Yam kom yaj cov ionic compound, dejCov molecules yuav tsum muaj peev xwm stabilize cov ions uas tshwm sim los ntawm kev tawg cov ionic daim ntawv cog lus. … Thaum koj tso cov khoom ionic hauv dej, cov dej molecules nyiam cov ions zoo thiab tsis zoo los ntawm cov siv lead ua.
