Cov qauv rau sodium zincate yog Na2ZnO2. Thaum peb ntxiv ib co sodium hydroxide rau daim zinc hlau ces sov nws a ntsev yog tsim namely, sodium zincate hydrogen gas tso tawm.

Tsis tas li cov lus nug yog, dab tsi yog cov mis rau sodium zincate?

H4Na2O4Zn

Ib tug kuj yuav nug, dab tsi yog lub xeev ntawm sodium zincate? Cov mis ntawm Sodium Zincate yog Na2ZnO2. Peb tuaj yeem tau txais Sodium Zincate Thaum peb sib tov qee cov zinc granules hauv sodium hydroxide. Ib tug compound yog tsim nrog hydrogen gas. Qhov sib xyaw uas tau tso rau hauv peb lub thawv hauv aqueous xeev.

Raws li qhov no, yuav ua li cas sodium zincate tsim?

Txais Cov Lus Teb: Thaum lub hauv paus reacts nrog ib tug hlau, ces cov hlau ntsev thiab hydrogen gas yog tsim . Thaum twg sodium hydroxide tov yog rhuab nrog zinc, ces sodium zincate thiab hydrogen gas tsim.

Dab tsi yog Valency ntawm Zincate?

Sodium Zincate yog tsim los ntawm Sodium cation (Na +) thiab Zincate anion (ZnO2-2), yog li, muab cov tshuaj formula ntawm Na2ZnO2. Ntawm no, zincate anion muaj valency 2.
