Concentrated thiab dilute xa mus rau qhov concentration ntawm ib acidic los yog cov khoom tseem ceeb hauv cov kuab tshuaj. 16 M HCl yog ntau concentrated tshaj 0.5 M daws ntawm tib yam kua qaub . Muaj zog thiab qaug zog xa mus rau lub peev xwm ntawm ib qho kua qaub los yog puag rau dissociate. A muaj zog acid yuav dissociate tag nrho hauv dej los tsim hydronium ions.

Ib yam li ntawd, nws raug nug, dab tsi ua rau cov kua qaub muaj zog lossis tsis muaj zog?

A qaug zog acid yog ib kua qaub uas ib nrab dissociates rau hauv nws ions nyob rau hauv ib tug aqueous tov los yog dej. Piv txwv li, a muaj zog acid tag nrho dissociates rau hauv nws cov ions hauv dej. Nyob rau tib lub concentration, tsis muaj zog acids muaj pH ntau dua muaj zog acids.

Tsis tas li ntawd, dab tsi yog dilute acid? A dilute acid yog hais tias nyob rau hauv uas cov concentration ntawm cov dej sib tov nyob rau hauv lub kua qaub yog siab tshaj qhov concentration ntawm cov kua qaub nws tus kheej. Piv txwv li, 5% sulfuric kua qaub yog a dilute acid.

Ib tug kuj yuav nug, qhov txawv ntawm ib tug qaug zog acid thiab ib tug dilute tov ntawm ib tug muaj zog acid?

TSIS TAU TXAIS - TSIS TAU TXAIS YOG LI AIDS QHOV CHAW UA HAUJ LWM HAUJ LWM HYDROGEN IONS thaum DISSOLVE IN Dej. DILUTE ACIDS - THAUM AIDS YOG DISSOLVE IN Dej IN RAWS LI NTAUB NTAWV NTAWM NO ACID COV AIDS YOG HU DILUTE ACIDS FOR EXAMPLE DILUTE HCL YOG IB TUG HLUB UA TSAUG DILUTE CARBONIC ACID.

Puas yog dilute HCl tsis muaj zog acid?

HCl yog ib tug muaj zog kua qaub , CH3COV is a qaug zog acid . Muaj zog thiab qaug zog acid xa mus rau cov degrees ntawm dissociation. HCl acid ionises tag nrho rau H+ thiab Cl- ions (uas yog, txog 100 tawm ntawm 100 molecules pub lawv cov hydrogen ion). Vim li no, dilute HCl acid muaj zog tshaj li cov concentrated acetic kua qaub.
