Sodium Aluminate (sodium Metaaluminate)
Cov Khoom Siv Lub Cev
Khoom siv sodium aluminate yog ib hom khoom alkaline muaj zog uas zoo li hmoov dawb lossis cov khoom me me, tsis muaj xim, tsis muaj ntxhiab thiab tsis saj, Tsis yooj yim hlawv thiab tsis tawg, Nws muaj kev yaj zoo thiab yooj yim yaj hauv dej, sai sai kom meej thiab yooj yim nqus cov dej noo thiab carbon dioxide hauv huab cua. Nws yooj yim rau precipitate aluminium hydroxide tom qab yaj hauv dej.
