Ntsev ( sodium chloride ) yog tsim los ntawm qhov zoo sodium ions sib txuas rau qhov tsis zoo chloride ions. Dej tau yaj ntsev vim tias qhov zoo ntawm cov dej molecules nyiam cov chloride ions tsis zoo thiab qhov tsis zoo ntawm cov dej molecules nyiam cov sodium ions zoo.

Tib neeg kuj nug, NaCl yaj ua li cas?

Sodium chloride ( NaCl ) yaj thaum dej molecules tsis tu ncua tua cov NaCl siv lead ua, rub tawm tus kheej sodium (Na+) thiab chloride (Cl) cov. Qhov no nonstop nres txuas ntxiv mus txog rau tag nrho NaCl crystal disintegrates.

Ib sab saum toj no, vim li cas cov ntsev zoo li NaCl nyob ua ke? Raws li tau hais ua ntej, tag nrho cov zaub mov tau faib ua ntsev yog tuav ua ke los ntawm ionic bonds. Cov kub yog qhov tshwm sim ntawm ib qho tshwj xeeb atomic kev npaj ntawm sodium thiab chlorine ions, uas yog Qhov tshwm sim ntawm ob qho tib si ionic nqi thiab ionic radii.

Ntxiv rau qhov no, yuav ua li cas thaum ntsev yaj?

Thaum twg ntsev yog tov nrog dej, lub ntsev dissolves vim covalent bonds ntawm cov dej muaj zog tshaj cov ionic bonds nyob rau hauv lub ntsev molecules. Cov dej molecules rub cov sodium thiab chloride ions sib nrug, rhuav tshem cov ionic daim ntawv cog lus uas tuav lawv ua ke.

Puas yog NaCl soluble hauv dej?

NaCl yog obviously soluble nyob rau hauv dej . NaCl yog aka hom ntsev thiab thaum nws dissolves nyob rau hauv dej nws yog hu ua ntsev dej uas koj tau hnov ua ntej. FYI, feem ntau ntawm sodium ntsev yaj nkag hauv dej vim siab hydration zog ntawm sodium ions.
