Kev tsim cov txheej txheem ntawm cerium nitrate:
Txoj kev nitric acid hydrolyzes acidic tov ntawm tsawg lub ntiaj teb hydroxide nplua nuj nyob rau hauv cerium, dissolves nrog nitric acid, thiab nyob rau hauv lub xub ntiag ntawm oxalic acid los yog hydrogen peroxide, txo 4 valent cerium rau 3 valent cerium. Tom qab crystallization thiab sib cais, cov khoom siv cerium nitrate tau npaj.
