Reacting tooj liab (II) oxide nrog sulfuric acid . Nyob rau hauv qhov kev sim no ib tug insoluble hlau oxide yog hnov mob nrog ib tug dilute kua qaub los ua ib tug soluble ntsev. Tooj (II) oxide , ib qho khoom dub, thiab tsis muaj xim dilute sulfuric acid teb tsim tawm tooj liab (II) sulfate, muab cov yam ntxwv xiav xim rau cov tshuaj.

Hauv qhov no, yuav ua li cas thaum tooj liab reacts nrog sulfuric acid?

Tooj tsis teb nrog dilute sulfuric acid raws li nws cov peev xwm txo tau siab dua li ntawm hydrogen. Tab sis, concentrated sulfuric acid yog oxidizing tus neeg sawv cev. Yog li, thaum tooj liab yog rhuab nrog conc. H2SO4 , ib redox tshuaj tiv thaiv tshwm sim thiab cov kua qaub tau txo kom sulfur dioxide.

tooj liab oxide tuaj yeem ua rau cov kua qaub? Ib metal- cov tshuaj tiv thaiv acid yog ib txwm redox tshuaj tiv thaiv . Txij li thaum tooj liab muaj peev xwm txo qis dua li hydrogen, nws ua tsis yog teb nrog tsis-oxidizing kua qaub zoo li HCl los yog dil. H2SO4. Tooj oxide yog lub hauv paus tsis muaj zog, thiab nws yooj yim reacts nrog HCl tsim soluble tooj liab (II) chloride thiab dej.

Hais txog qhov no, hom tshuaj tiv thaiv dab tsi yog tooj liab oxide thiab sulfuric acid?

Tooj (II) oxide yuav teb nrog sulfuric acid tsim dej thiab tooj liab (II) sulfate. Qhov no tshuaj tiv thaiv tuaj yeem muab faib ua ob qhov kev hloov pauv tshuaj tiv thaiv los yog neutralization tshuaj tiv thaiv (hlau oxides muaj cov khoom tseem ceeb hauv dej).

Vim li cas tooj liab tsis hnov mob nrog sulfuric acid?

Teb: Tooj liab tsis hnov mob nrog dilute sulfuric acid . Yog li ntawd, tsis muaj tshuaj tiv thaiv yuav siv qhov chaw thaum dilute sulfuric acid yog nchuav rau ib tooj liab phaj. Tab sis thaum concentrated sulfuric acid yog nchuav lawm tooj liab phaj, effervescence yog pom. Qhov no tshwm sim vim yog tsim cov roj hydrogen.
