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.

Yog vim li cas aluminium reacts nrog tooj liab chloride?
Aluminium hlau yog ib txwm them rau hauv nyias, tab sis tiv thaiv txheej ntawm aluminium oxide, Al2O3. Cov tshuaj chloride ion pab cais cov txhuas ntawm cov pa oxygen kom cov txhuas tuaj yeem ua rau cov tooj liab ions (thiab cov dej molecules)
Puas yog tooj liab oxide soluble hauv sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Yuav ua li cas thaum tooj liab oxide reacts nrog sulfuric acid?
Reacting tooj liab (II) oxide nrog sulfuric acid. Nyob rau hauv qhov kev sim no ib qho insoluble hlau oxide reacted nrog ib tug dilute acid los ua ib tug soluble ntsev. Tooj liab (II) oxide, cov khoom dub, thiab tsis muaj xim dilute sulfuric acid react los tsim tooj liab (II) sulfate, muab cov xim xiav xim rau cov tshuaj
Dab tsi yog qhov sib npaug ntawm tooj liab oxide thiab sulfuric acid?
Txhawm rau sib npaug CuO + H2SO4 = CuSO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug. Thaum koj paub ntau npaum li cas ntawm txhua hom atom koj tuaj yeem hloov pauv cov coefficients (tus lej nyob rau hauv pem hauv ntej ntawm atoms lossis cov tebchaw) kom sib npaug ntawm qhov sib npaug rau tooj liab (II) oxide + Sulfuric acid
Yuav ua li cas thaum tooj liab II chloride reacts nrog txhuas?
Thaum koj muab aluminium rau hauv tooj liab chloride, cov tooj liab ua ke cov chloride noj tam sim ntawm txhuas. Muaj qhov hnov ntxhiab tsw tsw thiab qee cov pa luam yeeb vim yog cov tshuaj tiv thaiv tshuaj. Raws li cov tooj liab chlorides ua haujlwm deb ntawm txhuas, cov txhuas tig mus rau hauv cov xim av tsaus
