Qhov sib txawv tseem ceeb ntawm binary acids thiab oxyacids yog tias cov oxyacids muaj tsawg kawg yog ib qho oxygen atom hauv molecule, tab sis cov binary acids tsis muaj oxygen. Binary acids muaj hydrogen thiab lwm yam tsis yog hlau nyob rau hauv lub molecule.
Peb tuaj yeem txhais cov kua qaub rau ntau txoj hauv kev raws li ntau tus kws tshawb fawb. Raws li lub Arrhenius los yog Bronsted-Lowry txhais, ib tug compound yuav tsum muaj ib tug hydrogen atom thiab yuav tsum muaj peev xwm pub nws li ib tug proton yog hais tias peb yuav muab nws lub npe raws li ib tug acid. Tab sis raws li Lewis, muaj cov molecules, uas tsis muaj hydrogen, tab sis tuaj yeem ua raws li cov kua qaub, piv txwv li BCl3 yog Lewis acid, vim nws tuaj yeem txais ib khub electron. Tsis hais txog hom saum toj no, peb tuaj yeem piav qhia thiab faib cov kua qaub rau ntau txoj hauv kev. Piv txwv li, raws li inorganic thiab organic acids nyob ntawm seb lawv muaj thiab kuj yog binary acids thiab oxyacids.
Dab tsi yog Binary Acids?
Binary acids yog cov molecules, uas muaj ob lub ntsiab lus; Ib qho yog hydrogen, thiab lwm qhov yog cov khoom tsis yog hlau, uas yog electronegative ntau dua li hydrogen. Yog li, binary acids tuaj yeem pub H+ ions hauv aqueous media. HCl, HF, HBr, thiab H2S yog qee qhov piv txwv rau binary acids. Cov no qhia cov khoom sib txawv thaum lawv nyob hauv daim ntawv ntshiab thiab thaum lawv nyob hauv aqueous media.
Nyob rau hauv lub npe ntawm binary acids, yog tias cov kua qaub nyob hauv daim ntawv ntshiab, lub npe pib nrog "hydrogen", thiab lub npe anionic xaus nrog "-ide". Piv txwv li, peb tuaj yeem hu HCl li hydrogen chloride. Aqueous binary acid kua npe pib nrog "hydro", thiab lub npe anion xaus nrog "ic". Nyob ntawd, peb ntxiv lo lus "acid" mus rau qhov kawg ntawm lub npe. Piv txwv li, aqueous HCl tov yog hydrochloric acid.

Ntxiv mus, peb tuaj yeem txiav txim siab lub zog ntawm binary acid los ntawm nws yooj yim npaum li cas pub H+ rau nruab nrab. Yog tias qhov sib txuas ntawm hydrogen thiab lwm yam khoom tsis muaj zog, nws tuaj yeem pub dawb rau cov proton; Yog li, cov kua qaub muaj zog dua. Kev ruaj ntseg ntawm cov tsim anion tseem cuam tshuam rau lub peev xwm pub dawb proton. Piv txwv li, HI yog cov kua qaub ntau dua HCl, vim tias I– anion ruaj khov dua li Cl– anion.
Oxyacids yog dab tsi?
Oxyacids yog cov kua qaub uas muaj cov pa atom hauv cov molecule. HNO3, H2SO4, H2 CO3, H3PO4, CH3 COOH yog qee yam ntawm cov oxyacids. Lwm yam tshaj li cov pa, muaj tsawg kawg yog ib lub caij thiab tsawg kawg yog ib qho hydrogen atom nyob rau hauv lub molecule.

Lub peev xwm pub dawb ib lossis ntau dua protons yog qhov tseem ceeb los ua kom lub cev muaj kua qaub. Lub hydrogen ntawm oxyacid khi nrog cov pa atom. Yog li ntawd, nyob rau hauv cov kua qaub no, peb tuaj yeem txiav txim siab acidity los ntawm electronegativity ntawm lub hauv paus atom thiab cov pa oxygen atoms.
Qhov txawv ntawm Binary Acids thiab Oxyacids yog dab tsi?
Binary acids yog cov molecules, uas muaj ob lub ntsiab lus; Ib qho yog hydrogen, thiab lwm qhov yog cov khoom tsis yog hlau. Txawm li cas los xij, oxyacids yog cov kua qaub uas muaj oxygen atom hauv cov molecule. Yog li, qhov sib txawv tseem ceeb ntawm binary acids thiab oxyacids yog tias cov oxyacids muaj tsawg kawg yog ib qho oxygen atom hauv cov molecule, tab sis cov binary acids tsis muaj oxygen.
Raws li lwm qhov sib txawv tseem ceeb ntawm binary acid thiab oxyacids, hauv oxyacids, cov proton uas tau pub dawb yog txuas nrog cov pa atoms. Hauv binary acids, cov hydrogens txuas nrog rau lwm cov khoom tsis yog hlau.
Hauv qab no yog ib qho infographic ntawm qhov sib txawv ntawm binary acid thiab oxyacids.
Summary – Binary Acids vs Oxyacids
Binary acids thiab oxyacids yog ob hom acidic compounds. Qhov sib txawv tseem ceeb ntawm binary acids thiab oxyacids yog tias oxyacids muaj tsawg kawg yog ib qho oxygen atom hauv cov molecule thiab binary acids tsis muaj oxygen. Binary acids muaj hydrogen thiab lwm yam tsis yog hlau nyob rau hauv lub molecule.
