Cov kua qaub tsis muaj zog, zoo li cov kua qaub muaj zog, ionize kom tawm los H +ion thiab lub hauv paus conjugate. Vim HCl yog ib tug muaj zog acid, nws conjugate puag (Cl −) yog qhov tsis muaj zog . Cov chloride ion tsis muaj peev xwm lees txais H +ion thiab dhau los ua HCl dua. Feem ntau, qhov muaj zog ntawm cov kua qaub, qhov tsis muaj zog nws lub hauv paus conjugate.
Vim li cas cov kua qaub tsis muaj zog tsis cuam tshuam tag nrho?
Ib lub kua qaub tsis muaj zog yog ib qho uas tsis cuam tshuam tag nrho hauv kev daws; Qhov no txhais tau hais tias cov kua qaub tsis muaj zog tsis pub tag nrho nws cov hydrogen ions (H+) hauv kev daws . … Yog li ntawd, qhov concentration ntawm H+ ions nyob rau hauv ib tug qaug zog acid tov yog ib txwm tsawg tshaj li cov concentration ntawm undissociated hom, HA.
Vim li cas cov kua qaub tsis muaj zog tsuas yog qee qhov ionizes?
Yog li cov acids muaj zog yog ionized tag nrho hauv cov kua dej vim tias lawv cov hauv paus conjugate yog cov hauv paus tsis muaj zog dua li dej. Cov kua qaub tsis muaj zog tsuas yog qee qhov ionized vim lawv cov hauv paus sib xyaw muaj zog txaus los sib tw nrog dej kom muaj cov protons.
Vim li cas equilibrium thiaj nyiam cov kua qaub tsis muaj zog?
tsis muaj zog acids thiab cov hauv paus yog qis zog dua muaj zog acids thiab cov hauv paus, thiab vim tias equilibria nyiam cov tshuaj tiv thaiv nrog cov hom qis tshaj plaws, cov tshuaj tiv thaiv acid yuav mus rau sab nrog cov tsis muaj zog acids thiab cov hauv paus. Raws li txoj cai, qhov sib npaug ntawm cov tshuaj tiv thaiv yuav nyiam sab nrog tsis muaj zogacids thiab bases.
YPuas yog ionisation ntawm ib tug qaug zog acid reversible?
Cov kua qaub muaj zog thiab cov hauv paus muaj zog hais txog cov tsiaj uas tsis sib haum xeeb los ua ions hauv kev daws. Los ntawm qhov sib txawv, cov acids tsis muaj zog thiab cov hauv paus ionize tsuas yog ib feem, thiab ionization cov tshuaj tiv thaiv yog thim rov qab.

Puas yog carbonic acid yog cov kua qaub uas muaj zog?
Hydrochloric acid (HCl) yog suav tias yog cov kua qaub uas muaj zog vim tias nws tsuas yog muaj nyob rau hauv daim ntawv ionized nkaus hauv lub cev, whereas carbonic acid (H 2CO 3 ) yog cov kua qaub tsis muaj zog vim nws yog ionized tsis tiav, thiab, ntawm qhov sib npaug, tag nrho peb cov reactants muaj nyob rau hauv lub cev kua.
Dab tsi ntawm cov hauv qab no yog cov kua qaub uas muaj zog tshaj chloroacetic acid?
Yog li, los ntawm cov kev xaiv tau muab, trichloroacetic acid yuav yog cov kua qaub uas muaj zog tshaj plaws vim tias muaj peb chlorine atoms tam sim no ntawm tib cov pa roj carbon uas yuav cuam tshuam cov nqi tsis zoo tshaj plaws thiab ua rau Qhov ruaj khov tshaj plaws carboxylate ion.
Puas muaj cov kua qaub uas muaj zog ionised hauv dej?
(siab dua) Cov kua qaub muaj zog ua tiav ionise hauv dej. Lawv rhuav tshem tag nrho los tsim kom muaj cov ntsiab lus siab ntawm hydrogen ions hauv cov tshuaj. Vim li cas cov kua qaub muaj zog ionize tag nrho hauv dej? Ib qho kua qaub lossis lub hauv paus lub zog hais txog nws qib ntawm ionization.
Puas yog cov kua qaub tsis muaj zog ionize hauv dej?
Ib lub zog acid yuav ua tiav hauv dej thaum tsis muaj kua qaub tsuas yog qee qhov ionize. Puas tsis muaj zog acids dissociate los yog ionize? Tsis muaj Acids Cov kua qaub muaj zog yog 100% ionized hauv cov tshuaj. Cov kua qaub tsis muaj zog tsuas yog me ntsis ionized.
Puas yog sulfamic acid yog cov kua qaub muaj zog?
Sulfamic Acid yog a muaj zog acid (pKa=1.0) thiab dissociates tag nrho hauv cov tshuaj aqueous. Lub pH ntawm qhov sib npaug point qhov sib npaug Qhov sib npaug taw tes, los yog stoichiometric taw tes, ntawm cov tshuaj tiv thaiv tshuaj yog qhov taw tes ntawm cov tshuaj sib npaug ntawm cov tshuaj reactants tau tov.
