Qhov sib txawv tseem ceeb ntawm binary acids thiab polyatomic acids yog tias binary acids muaj cov atoms los ntawm tsuas yog ob yam tshuaj sib txawv, hos polyatomic acids muaj atoms los ntawm ob lossis ntau cov tshuaj sib txawv.
Ib qho kua qaub yog cov tshuaj inorganic uas tuaj yeem ua rau cov tshuaj alkaline neutralize. Cov kua qaub muaj peev xwm yaj tau cov hlau feem ntau. Peb tuaj yeem txheeb xyuas cov kua qaub uas siv cov ntawv litmus - xiav litmus hloov mus rau xim liab thaum nws ntub nrog cov kua qaub. Muaj ntau hom acids; binary acids thiab polyatomic acids yog ob hom.
Dab tsi yog Binary Acids?
Binary acids yog cov khoom tsis muaj zog uas muaj hydrogen-bonded rau lwm cov tshuaj lom neeg. Cov tshuaj thib ob no feem ntau yog cov khoom tsis yog xim hlau. Lo lus "binary" yog hais txog ib yam khoom uas muaj "ob" ntawm ib yam dab tsi; Hauv cov ntsiab lus no, nws yog ob yam tshuaj sib txawv. Lub acidity ntawm cov tshuaj no tshwm sim vim lawv muaj peev xwm tso tawm hydrogen raws li ib tug cation los yog proton, uas ua rau lub acidity ntawm nws aqueous tov. Feem ntau cov binary acids muaj xws li hydrofluoric acid (HF), hydrochloric acid (HCl), thiab hydrobromide acid (HBr). Ntxiv mus, binary acids tej zaum yuav muaj ib los yog ntau dua hydrogen atoms ib molecule, nyob ntawm seb qhov valency ntawm cov nonmetal uas yog bonded rau hydrogen atom (s), piv txwv li. H2S.
Daim duab 01: Hydrogen Chloride
Binary acids tuaj yeem yog cov kua qaub uas muaj zog, cov kua qaub tsis muaj zog lossis cov kua qaub me ntsis. Lub zog acidic no nyob ntawm lub zog ntawm covalent daim ntawv cog lus ntawm hydrogen atom thiab nonmetallic atom. Txij li tag nrho cov binary acids muaj hydrogen atoms, lub npe ntawm binary acid pib nrog "hydro-".
YPolyatomic Acids yog dab tsi?
Polyatomic acids yog inorganic compounds uas muaj atoms nrog ob los yog ntau tshaj cov tshuaj sib txawv. Txawm li cas los xij, cov ions uas tsim los ntawm kev sib cais ntawm polyatomic acid tuaj yeem yog monoatomic lossis polyatomic vim qee cov polyatomic acids tsuas muaj ob yam tshuaj sib txawv thiab kev tshem tawm ntawm hydrogen atom tsim monoatomic ion.
Daim duab 02: Cov qauv ntawm Sulfuric Acid
Qee cov piv txwv ntawm polyatomic acids muaj xws li carbonic acid (H2CO3), sulfuric acid (H2SO4), sulfurous acid (H2SO3), nitric acid (HNO3), thiab lwm yam.
Qhov txawv ntawm Binary Acids thiab Polyatomic Acids yog dab tsi?
Ib qho kua qaub yog ib yam khoom uas tuaj yeem ua rau cov tshuaj alkaline neutralize. Qhov sib txawv tseem ceeb ntawm binary acids thiab polyatomic acids yog tias binary acids muaj cov atoms los ntawm tsuas yog ob yam tshuaj sib txawv, hos polyatomic acids muaj atoms los ntawm ob los yog ntau dua cov tshuaj sib txawv.
Ntxiv mus, binary acids ib txwm tsim lub hauv paus monoatomic conjugate, thaum polyatomic acids tuaj yeem tsim lub hauv paus monoatomic conjugate lossis polyatomic puag. Tsis tas li ntawd, binary acids feem ntau muaj zog mus rau nruab nrab acids. Hydrofluoric acid (HF), hydrochloric acid (HCl), thiab hydrobromide acid (HBr) yog ib co piv txwv ntawm binary acids. Polyatomic acids, ntawm qhov tod tes, tuaj yeem yog cov kua qaub uas muaj zog, cov kua qaub tsis muaj zog lossis cov kua qaub nruab nrab. Qee qhov piv txwv suav nrog carbonic acid (H2CO3), sulfuric acid (H2SO4), thiab nitric acid (HNO3).
Hauv qab infographic tabulates ib sab ntawm qhov sib txawv ntawm binary acids thiab polyatomic acids.
Summary – Binary Acids vs Polyatomic Acids
Peb tuaj yeem txheeb xyuas cov kua qaub yooj yim siv cov ntawv litmus; xiav litmus hloov liab thaum soaked nrog ib tug acid. Muaj ntau hom acids, xws li binary acids thiab polyatomic acids. Qhov sib txawv tseem ceeb ntawm binary acids thiab polyatomic acids yog tias binary acids muaj cov atoms los ntawm tsuas yog ob yam tshuaj sib txawv, hos polyatomic acids muaj atoms los ntawm ob los yog ntau dua cov tshuaj sib txawv.
