Dab tsi yog siv sodium?
Sodium Nws yog siv los ua cov khoom siv hluav taws xob sib hloov hauv cov khoom siv hluav taws xob, thiab ua cov reagent hauv kev lag luam tshuaj. Tab sis sodium ntsev muaj ntau dua siv tshaj cov hlau nws tus kheej. Qhov feem ntau compound ntawm sodium yog sodium chloride (xws li ntsev). Nws yog ntxiv rau zaub mov thiab siv los de-ice txoj kev nyob rau lub caij ntuj no.
