tooj liab ua tsis yog teb nrog dilute sulfuric acid raws li nws cov peev xwm txo tau siab dua li ntawm hydrogen. tooj liab ua tsis hloov hydrogen los ntawm tsis-oxidizing kua qaub zoo li HCl los yog dilute H2SO4 . 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.

Ua li no, 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.

Qhov thib ob, puas tooj liab ua rau cov kua qaub? tooj liab ua tsis yog teb nrog tsis-oxidizing kua qaub zoo li hydrochloric kua qaub los yog dilute sulfuric kua qaub . Raws li nws cov electrode (txo) muaj peev xwm siab dua li ntawm hydrogen, ntshiab tooj liab tsis tuaj yeem tshem tawm hydrogen los ntawm qhov no kua qaub . Tab sis tooj liab yooj yim reacts nrog oxidizing kua qaub zoo li nitric kua qaub thiab kub, concentrated sulfuric kua qaub.

Tsis tas li ntawd, puas tooj liab hydroxide react nrog sulfuric acid?

Hauv neutralization tshuaj tiv thaiv tooj liab hydroxide ib base reacts nrog sulfuric acid ua form tooj liab sulfate. Nws yog ib txwm ntsev tam sim no nyob rau hauv hydrated thiab anhydrous daim ntawv.

Puas yog CuSO4 react nrog h2so4?

Nco ntsoov sulfuric acid yog ib tug tshwj xeeb muaj zog dehydrating neeg sawv cev thiab nyob rau hauv kev sib cuag nrog CuSO 4 . 5H2O nws dehydrates xiav crystals thiab tawm anhydrous, tab sis dawb, tooj liab (II) sulfate.
