Kev tsim
Tooj liab (II) hydroxide tuaj yeem tsim los ntawm kev ntxiv sodium hydroxide rau ntau tus tooj liab (II) qhov chaw. Qhov xwm ntawm lub txiaj ntsig tooj liab (II) hydroxide txawm li cas los xij rhiab rau cov ncauj lus kom ntxaws. Qee txoj kev tsim cov tub ntxhais me, khov kho tooj liab (II) hydroxide thaum lwm txoj kev tau tsim tawm qhov ntsuas kub kev khi- Zoo li khoom.
Ib txwm muaj kev daws teeb meem ntawm cov tooj liab soluble (II) ntsev, xws li Tooj liab (II) sulfate (Cuso4H · 5to) yog kho nrog lub hauv paus:
- 2Nsoh + Cuso4 · 5O → CU (Oh) 2 + 6h2o + NA2O4
Daim ntawv no tooj liab hydroxide nyhav hloov mus rau dub Tooj liab (II) oxide:
- Cu (Oh)2 → Cuo + H2O
