Qhov Tseem Ceeb Qhov txawv - Binary vs Ternary Acids
Acids yog cov sib txuas uas muaj peev xwm pub cov hydrogen ions (H+) los yog tsim cov ntawv cog lus nrog ib khub electron (ib Lewis acid). Acids muaj ntau yam yam ntxwv xws li muaj peev xwm tig xiav Litmus mus rau hauv cov xim liab, neutralize alkaline daws, thiab lwm yam. Feem ntau cov acids yog corrosive txawm tias tsawg concentrations. Yog li ntawd, yuav tsum tau saib xyuas thaum ua haujlwm nrog cov kua qaub. Binary thiab ternary acids yog ob hom acids. Qhov sib txawv tseem ceeb ntawm binary thiab ternary acids yog tias binary acids yog cov tshuaj sib xyaw ua ke uas muaj hydrogen ua ib qho tseem ceeb ntawm cov khoom sib txuas rau cov hlau tsis yog hlau hos ternary acids yog cov kua qaub uas muaj hydrogen thiab oxygen atoms sib txuas rau lwm lub caij, feem ntau ntawm lub sijhawm., ib nonmetal.
Dab tsi yog Binary Acids
A binary acid yog ib qho acidic compound uas ib txwm muaj hydrogen pob txha mus rau lwm cov tshuaj, feem ntau ntawm cov nonmetal. Nws yog hu ua "binary" vim nws muaj ob yam sib txawv ua ke nrog ib leeg. Txij li thaum hydrogen tam sim no yog ib qho tseem ceeb ntawm cov khoom, binary acids kuj hu ua hydracids. Binary acids yog covalent compounds uas ua raws li cov kua qaub nyob rau hauv ib qho nruab nrab aqueous.
Lwm cov hlau uas ua ke nrog hydrogen atom ntawm no yog p block element. Txawm hais tias cov kua qaub no tsuas yog tsim los ntawm ob lub ntsiab lus sib txawv, lawv tsis yog qhov tseem ceeb diatomic. Diatomic compounds yog cov molecules uas muaj ob lub atoms. Binary acids tuaj yeem yog diatomic lossis tuaj yeem muaj ntau dua ob lub atoms ib molecule.
Daim duab 01: H2S yog Binary Acid
Binary acids muaj hydrogen ion (H+) ua cov cation nkaus xwb. Yog li ntawd, thaum lub npe binary acid, cov khoom hauv qab no yuav tsum nyob ntawd.
- The prefix 'hydro-'
- lub hauv paus npe ntawm anion
- Suffix '–ic' ua raws li lo lus acid
Cia peb xav txog qee qhov piv txwv ntawm binary acids.
Ternary Acids yog dab tsi?
Ternary acids yog cov tshuaj acidic uas muaj hydrogen thiab oxygen ua ke nrog lwm cov khoom. Lwm yam tshuaj yog feem ntau ntawm lub sij hawm, ib tug nonmetal. Nws yog ib qho kev sib xyaw ua ke ntawm hydrogen ion (H+) bonded rau polyatomic anion. Txawm li cas los xij, hydrogen ion tsuas yog cation muaj nyob hauv ternary acids.
Ternary acids feem ntau hu ua "oxyacids". Tias yog vim hais tias cov no yog cov pa oxygen muaj cov tebchaw uas muaj peev xwm tso tawm hydrogen ion (H+) mus rau qhov nruab nrab aqueous uas nws yaj hauv. Li no, cov qauv dav dav rau ternary acid. yog “H-O-X”.
Yuav ua kom cov kua qaub, qhov sib xyaw no yuav tsum pub cov hydrogen ions los ntawm kev rhuav tshem cov ntawv cog lus ntawm hydrogen atoms thiab cov pa atom (-O-H). Rau qhov no tshwm sim, cov nonmetal bonded rau oxygen (X) yuav tsum tau electronegative heev. Tom qab ntawd, cov electrons tau ntxim nyiam los ntawm cov hlau tsis yog hlau, thiab vim li ntawd, kev sib raug zoo ntawm oxygen thiab hydrogen tsis muaj zog.
Daim duab 02: Sulfuric Acid yog Ternary Acid
Thaum naming ternary acids, cov lus kawg ntawm cov npe ntawm anions raug hloov (raws li oxidation lub xeev ntawm cov nonmetal) ua raws li lo lus "acid". Hauv qab no yog qee qhov piv txwv.
Dab tsi zoo sib xws ntawm Binary thiab Ternary Acids?
- Ob lub Binary thiab Ternary Acids yog cov qauv ntawm cov kua qaub.
- Ob lub Binary thiab Ternary Acids muaj peev xwm pub nyiaj hydrogen ions.
- Ob lub Binary thiab Ternary Acids yog tsim los ntawm hydrogen atoms.

Summary – Binary vs Ternary Acids
Binary acids yog cov tebchaw uas muaj cov qauv dav dav H-X. Ternary acids yog cov tshuaj acidic uas muaj cov qauv dav dav H-O-X. Qhov sib txawv ntawm binary thiab ternary acids yog tias binary acids yog cov tshuaj sib xyaw ua ke uas muaj hydrogen ua ib qho tseem ceeb ntawm cov khoom sib txuas rau cov hlau tsis yog hlau hos ternary acids yog cov kua qaub uas muaj hydrogen thiab oxygen atoms sib txuas rau lwm lub caij, feem ntau ntawm cov sij hawm, ib nonmetal.
