Qhov sib txawv tseem ceeb ntawm hydrofluoric acid thiab hydrochloric acid yog tias hydrofluoric acid yog cov kua qaub tsis muaj zog thaum lub hydrochloric acid yog cov kua qaub. Tsis tas li ntawd, cov hydrofluoric acid muaj peev xwm tsim tau hydrogen bonds thaum lub hydrochloric acid tsis tuaj yeem tsim hydrogen bonds.
Ntxiv mus, ib qho tseem ceeb sib txawv ntawm hydrofluoric acid thiab hydrochloric acid yog nyob rau hauv lawv cov qauv molecular. Lub hydrofluoric acid molecule muaj fluoride ion thaum lub hydrochloric acid molecule muaj chloride ion. Ntxiv mus, ob qho tib si hydrofluoric thiab hydrochloric acid yog proton pub. Yog li ntawd, cov kua qaub molecules tuaj yeem ionize hauv cov nruab nrab aqueous tso tawm protons (H+). Cov protons no ua rau cov kua qaub hauv cov dej nruab nrab.
Hydrofluoric Acid yog dab tsi?
Hydrofluoric acid yog hydrogen fluoride hauv dej. Hydrogen fluoride yog ib qho acidic compound uas muaj cov tshuaj formula HF thiab molar mass 20 g / mol. Tsis tas li ntawd, cov kua qaub no yog qhov pib sib xyaw rau yuav luag tag nrho cov fluorine-muaj cov khoom sib txuas. Piv txwv li: Teflon. Cov kua qaub no zoo heev nrog iav thiab nruab nrab reactive nrog hlau. Yog li ntawd, nws yog khaws cia rau hauv cov thawv yas. Txawm li cas los xij, lub thawv ua los ntawm Teflon yog me ntsis permeable rau cov kua qaub no.
Daim duab 01: Ib Lub raj mis ntawm Hydrofluoric Acid
Hydrofluoric acid yog cov kua qaub tsis muaj zog. Qhov ntawd yog vim nws muaj qis dissociation tas li. Lub dissociation ntawm cov kua qaub no muab hydronium ions (kev sib txuas ntawm protons thiab dej molecules tsim hydronium ions) thiab fluoride ions. Ntawm cov hydrohalic acids, qhov no tsuas yog tsis muaj zog acid. Peb tuaj yeem tau txais cov kua qaub no los ntawm kev ntxiv cov concentrated sulfuric acid rau cov ntxhia fluorite (CaF2).
Hydrochloric Acid yog dab tsi?
Hydrochloric acid yog ib qho aqueous hydrogen chloride. Hydrogen chloride muaj cov tshuaj formula HCl, thiab nws cov molar loj yog 36.5 g / mol. Cov kua qaub no muaj pungent tsw. Ntxiv mus, nws yog ib qho tseem ceeb ua ib qho chaw pib rau ntau cov tshuaj inorganic xws li vinyl chloride.
Daim duab 02: Ib Lub raj mis ntawm Hydrochloric Acid
Tsis zoo li HF, HCl yog cov kua qaub uas muaj peev xwm ua tiav ionize hauv nruab nrab aqueous, tsim hydronium ions thiab chloride ions. Yog li, cov kua qaub no muaj cov nqi siab Ka. Peb tuaj yeem npaj cov kua qaub no los ntawm kev kho HCl nrog dej.
Qhov txawv ntawm Hydrofluoric Acid thiab Hydrochloric Acid yog dab tsi?
Hydrofluoric acid yog hydrogen fluoride hauv dej. Nws yog ib qho tsis muaj zog acid, thiab nws tuaj yeem tsim hydrogen bonds. Hydrochloric acid yog aqueous hydrogen chloride. Nws yog ib qho muaj zog acid, thiab nws tsis tuaj yeem tsim hydrogen bonds. Qhov no yog qhov txawv ntawm hydrofluoric acid thiab hydrochloric acid.
Ntxiv mus, hydrofluoric acid molecule muaj fluoride ion hos cov hydrochloric acid molecule muaj chloride ion. Txawm li cas los xij, ob qho tib si no yog hydrohalic acids uas muaj hydrogen atom txuas rau halogen. Ntxiv mus, hydrofluoric acid yog tib cov kua qaub tsis muaj zog ntawm lwm cov hydrohalic acids.
Summary – Hydrofluoric Acid vs Hydrochloric Acid
Hydrofluoric thiab hydrochloric acid yog hydrohalic acids vim hais tias ob qho tib si cov kua qaub no muaj halide khi rau hydrogen atom. Ntxiv mus, muaj ntau qhov sib txawv ntawm ob cov kua qaub no. Qhov sib txawv ntawm hydrofluoric acid thiab hydrochloric acid yog tias hydrofluoric acid yog cov kua qaub tsis muaj zog thiab nws tuaj yeem tsim cov ntawv cog lus hydrogen whereas hydrochloric acid yog cov kua qaub muaj zog thiab nws tsis muaj peev xwm tsim cov ntawv cog lus hydrogen.
