Cov cuab yeej ntawm lub cev yog cov yam ntxwv ntawm cov khoom uas tuaj yeem soj ntsuam lossis ntsuas yam tsis hloov tus kheej ntawm cov khoom. Lub cev muaj zog suav nrog xim , ceev , hardness, thiab melting thiab boiling ntsiab lus. Cov cuab yeej Achemical piav qhia txog lub peev xwm ntawm cov khoom siv los hloov pauv tshuaj lom neeg.
Tsis tas li ntawd, cov cuab yeej twg yog tus yam ntxwv ntawm cov khoom ntshiab uas tuaj yeem pom tau?
Txhua hom teeb meem muaj ob hom khoom - lub cev khoom thiab tshuaj khoom . Lub cev Cov khoom : Ib lub cev Cov cuab yeej yog ib yam ntxwv ntawm cov khoom ntshiab uas tuaj yeem pom tau tsis hloov nws mus rau lwm qhov yam khoom.
Qhov thib ob, yam khoom twg tuaj yeem pom yam tsis hloov cov khoom? Lub cev khoom yog khoom uas ua tau ntsuas los yog pom yam tsis hloov thechemical xwm ntawm lub yam khoom . Qee qhov piv txwv ntawm lub cev khoom yog: xim (intensive) ceev (intensive)
Tsis tas li ntawd, cov khoom ntawm ib yam khoom yog dab tsi?
Tus general khoom ntawm cov teeb meem xws li xim, ntom, hardness, yog cov piv txwv ntawm lub cev khoom . Cov khoom uas piav li cas a yam khoom hloov mus rau qhov sib txawv kiag li yam khoom hu ua chemical khoom . Flammability thiab corrosion / oxidation resistance yog cov piv txwv ntawm cov tshuaj khoom.
Yuav ua li cas yuav tsum tau soj ntsuam cov yam ntxwv ntawm ib yam khoom?
Cov khoom siv tshuaj tsuas yog tsim los ntawm kev hloov pauv a tshuaj chemical tus kheej, thiab txawv ntawm lub cev khoom , uas tau pom los ntawm kev saib lossis kov ib qho qauv. Internal qualities ntawm a khoom yuav tsum hloov los txiav txim nws chemical khoom.

Yuav ua li cas koj txiav txim siab yog hais tias ib yam khoom yog acidic los yog yooj yim?
Txhawm rau txiav txim siab seb cov khoom puas yog acid orabase, suav cov hydrogens ntawm txhua yam khoom ua ntej thiab tom qab cov tshuaj tiv thaiv. Yog hais tias tus naj npawb ntawm hydrogenshas txo cov tshuaj yog cov kua qaub (donates hydrogen ions). Yog tias tus naj npawb ntawm hydrogens tau nce ntxiv tias cov khoom yog lub hauv paus ( lees txais hydrogenions )
